+Some faces will not be shown on some versions of Emacs unless you

+
+`fill-paragraph' on a comment may leave the point behind the
+paragraph. Parsing of lines with several <<EOF is not implemented
+yet.
+
+Emacs had a _very_ restricted syntax parsing engine until version
+20.1. Most problems below are corrected starting from this version of
+Emacs, and all of them should be fixed in version 20.3. (Or apply
+patches to Emacs 19.33/34 - see tips.) XEmacs was very backward in
+this respect (until 2003).
+
+Note that even with newer Emacsen in some very rare cases the details
+of interaction of `font-lock' and syntaxification may be not cleaned
+up yet. You may get slightly different colors basing on the order of
+fontification and syntaxification. Say, the initial faces is correct,
+but editing the buffer breaks this.
+
+Even with older Emacsen CPerl mode tries to corrects some Emacs
+misunderstandings, however, for efficiency reasons the degree of
+correction is different for different operations. The partially
+corrected problems are: POD sections, here-documents, regexps. The
+operations are: highlighting, indentation, electric keywords, electric
+braces.
This may be confusing, since the regexp s#//#/#\; may be highlighted
as a comment, but it will be recognized as a regexp by the indentation
-code. Or the opposite case, when a pod section is highlighted, but
+code. Or the opposite case, when a POD section is highlighted, but
may break the indentation of the following code (though indentation
should work if the balance of delimiters is not broken by POD).
The main trick (to make $ a \"backslash\") makes constructions like
${aaa} look like unbalanced braces. The only trick I can think of is
-to insert it as $ {aaa} (legal in perl5, not in perl4).

+(defvar cperl-speed 'please-ignore-this-line
+ "This is an incomplete compendium of what is available in other parts
+of CPerl documentation. (Please inform me if I skept anything.)
+
+There is a perception that CPerl is slower than alternatives. This part
+of documentation is designed to overcome this misconception.
+
+*By default* CPerl tries to enable the most comfortable settings.
+From most points of view, correctly working package is infinitely more
+comfortable than a non-correctly working one, thus by default CPerl
+prefers correctness over speed. Below is the guide how to change
+settings if your preferences are different.
+
+A) Speed of loading the file. When loading file, CPerl may perform a
+scan which indicates places which cannot be parsed by primitive Emacs
+syntax-parsing routines, and marks them up so that either
+
+ A1) CPerl may work around these deficiencies (for big chunks, mostly
+ PODs and HERE-documents), or
+ A2) On capable Emaxen CPerl will use improved syntax-handlings
+ which reads mark-up hints directly.
+
+ The scan in case A2 is much more comprehensive, thus may be slower.
+
+ User can disable syntax-engine-helping scan of A2 by setting
+ `cperl-use-syntax-table-text-property'
+ variable to nil (if it is set to t).
+
+ One can disable the scan altogether (both A1 and A2) by setting
+ `cperl-pod-here-scan'
+ to nil.
+
+B) Speed of editing operations.
+
+ One can add a (minor) speedup to editing operations by setting
+ `cperl-use-syntax-table-text-property'
+ variable to nil (if it is set to t). This will disable
+ syntax-engine-helping scan, thus will make many more Perl
+ constructs be wrongly recognized by CPerl, thus may lead to
+ wrongly matched parentheses, wrong indentation, etc.
+
+ One can unset `cperl-syntaxify-unwind'. This might speed up editing
+ of, say, long POD sections.")
