Re: What's the exact rule about hash/pound?

Comments are anything starting with an unquoted #, or a # character that's not part of a term.

%# = ( foo => 'bar', baz => 'buz' );
print keys( %# ), "\n";

Unfortunately, you can't access an element of that hash directly because it looks like you want the last element of an array. Bug? Maybe, but I sure don't want to fix it.

Update: Oh yeah, but yuck.

IlyaM has said how to do it right, so I figured I will say how to do it wrong. `:)` This is bad, ugly, and deprecated, but it works: `%#->{foo}` If you want to stay legal you can do it semi-direct: `(\%#)->{foo}` While on the theme of references: `no strict 'refs'; '#'->{foo}` [download] which will work since `%#` can't be private. But don't do any of the above. `ihb` It's labeled as a "known problem" in perl561delta, but in perl580delta it's called deprecated.	[reply] [d/l] [select]
