Many operators/builtins not separated from following single quote

[moregan]

PPI::Token::Word has code to make sure that some operators/builtins (eq ne ge le gt lt q qq qx qw qr m s tr y pack unpack) are separated from an immediately-following single quote because that’s what perl does. E.g.: “ $foo eq’bar’ “ is parsed by PPI and by perl as a symbol, the eq operator, and a single-quoted string. However, there are many words that perl separates that PPI does not, e.g.: ‘cmp’:

ppidump "\$foo cmp'bar'"
                    PPI::Document
                      PPI::Statement
[    1,   1,   1 ]     PPI::Token::Symbol       '$foo'
[    1,   6,   6 ]     PPI::Token::Word         'cmp'bar'
[    1,  13,  13 ]     PPI::Token::Quote::Single        '''

There are dozens of words PPI::Token::Word doesn't handle in regen/keywords.pl of the perl sources. Presumably most (all?) of them should be handled.

See Perl-Critic/Perl-Critic#451 for a real-world example.
