Re: Net::SMTP attachments?

That's why I said "bury". The basic problem here is a conflict between a mindset that builds stuff up from smaller parts, and the needs of people who need to use the higher level stuff. Building up from components is good for many reasons. But people who want to buy a car don't expect to be handed

Re: Need help with a match

You have two problems: (1) matches start from 0, not 1. (2) .* gobbles as much as possible (this is also true in Perl 5) so it matches to the ) at the end of (Sub|63218616). As in Perl 5, you add a ? to make it take the shortest match instead: #!/usr/bin/perl6 my $x='sub Test () { #`(Sub|63218616

Re: more match humility

Just to be a little more clear about what is happening here: Perl 5 tended to treat things as strings if you use them as strings, or as numbers if you use them as numbers. Perl 6 is more strict about that, but makes an exception for specifically numbers and strings; if you have noticed the class "
