Perl Grammar
You perhaps don't notice this, but the Perl 5 grammar is constantly evolving. There is no One True Perl 5 Grammar. From
5.8.0 to today's bleadperl, I count 50 changes to toke.c and perly.y -- vstrings,
defined-or operator, stack overflow fixes, utf8 barewords, scoping
changes, weird constructs in double-quoted strings, behaviour of '=>',
etc. All changes in hope of improving its dwimmery.
Or is it a BUG?"
"Let's call it an accidental feature. :-)"
