-----------------------------
you could shorten the regular expression for variable names
substituting a-zA-Z with A-z. These are exactly the same
character sets.
-----------------------------
'Z' is ASCII 90 and 'a' is ASCII 97; 91-96 ([, , ], ^, _,
`) lie between uppercase and lowercase. No, A-z is *not*
exactly the same character set as A-Za-z
