You have skipped one question:
Nope. Language designer call. (Granted, in this case if the call is "make it work" then the language designer and I get to have a chat, but... :)
how would PIR code of this eval() look like, and specifically, what about that "goto"?
That goto's bogus and shouldn't work. I think it does right now, but I'm OK with making it not work -- it *shouldn't*, since in perl the eval's an anonymous sub, which means you've done a goto out of a sub and into another, which... well, that's not supposed to work.
# #! perl -w
# my $i= 5;
# LAB:
# $i++;
# eval("goto LAB if ($i==6)");
# print "$i\n";
#
# 7

I can see this having some ramifications for languages with REPL facilities and goto, but I'm not sure I have a problem with that not working right.
