Heredoc issue in pugs.
#!/usr/bin/env pugs my $a = q:t /END/ test END; $a.perl.say; Above example works ok in pugs, But the problem is. From S02 Heredocs are no longer written with , but with an adverb on any other quote construct: print qq:to/END/; Give $amount to the man behind curtain number $curtain. END Which is correct?

See the table further down that says: : : What about the semicolon? After the terminator, or after the opening : line? Ah, missed that, thanks. On the opening line is correct, just as in Perl 5. The heredoc is just a term with some indirection, and the indirection is completely line oriented. The terminator must still be on a line by itself, with nothing but whitespace. We could just as easily have a POD indirection that said print qq:from/FOO/; and it would go looking for the nearest =begin FOO block to insert. So syntactically, it's only sort of happenstance that with heredocs the document happens to be here. The inline-ness of it is secondary to the line-orientedness of it, in my mind. And it is often not, in fact, truly inline, as demonstrated by print qq:to/FOO/, qq:to/BAR/; ... FOO ... BAR It's really just a way to abstract a large string containing newlines into a single token that doesn't. Larry

Well, that's kinda why theres's no :from actually. It was probably not beneficial to bring in a counterfactual example. Pod docs would actually come in through %=PODFOO or some such. Heredocs are a little more special because they have to interpolate from the local lexical pad, so in that sense they really are a bit more in-line-ish. Larry

If I remember correctly, Larry and Audrey discussed this at the Chicago hackathon and updated the Synopsis at that time. So my guess is that the Synopsis is correct. -kolibrie
