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
+two element list, binding its elements to symbols named `foo' and
`bar' -- in much the same way that `cl-destructuring-bind' would.
A significant difference from `cl-destructuring-bind' is that, if
succesful match is found or there are no more cases.
Another difference is that pattern elements may be backquoted,
-meaning they must match exactly: The pattern (\\='foo \\='bar)
+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
