you got me on this one ...
I wanted to reply that the Perl interpreter (with warnings enabled) would happily warn about it. But then I performed a short test:
"this_is_a_perl_3012_keyword" doesn't trigger a warning, neither do "thisisaperl3012keyword" nor "this_is_a_perl_keyword" whereas
"thisisaperlkeyword" does. Seems to be some weird promise: Perl keywords will never contain underscores or digits.
Another distinction mechanism, hooray!
