CASES is a list of elements of the form (PATTERN CODE...).
A structural PATTERN describes a template that identifies a class
-of values. For example, the pattern `(,foo ,bar) matches any
+of values. For example, the pattern \\=`(,foo ,bar) matches any
two element list, binding its elements to symbols named `foo' and
`bar' -- in much the same way that `cl-destructuring-bind' would.
a pattern match fails, the next case is tried until either a
successful match is found or there are no more cases.
-Another difference is that pattern elements may be backquoted,
+Another difference is that pattern elements may be quoted,
meaning they must match exactly: The pattern \\='(foo bar)
matches only against two element lists containing the symbols
`foo' and `bar' in that order. (As a short-hand, atoms always
match themselves, such as numbers or strings, and need not be
-quoted).
+quoted.)
Lastly, a pattern can be logical, such as (pred numberp), that
matches any number-like element; or the symbol `_', that matches
