good heavens.. the actual subroutine name is semi-colon?? So the name isn't
missing and isn't null, but is ';'. I'm not sure that that doesn't make it
MORE confusing to me --- Are there other punctuation marks that work in that
context??
Three questions:
1) is semicolon the ONLY puncuation mark that has this odd special-dispensation?
2) WHY does perl allow this --- it still seems like a slam-dunk syntax error
situation to me
3) who *discovered* this anomaly? [how does someone even think to TRY something
bizarre like this.....]
I'm not much of a golf fan but I've certainly learned interesting/amazing
things about Perl from the 'holes'.
