It's the push line I'm having difficulty with. Here's what I understand:
The outermost {} can be removed to simplify it to :
push( @$children{$v}, $k);
You understand incorrectly.
If it was @{ $foo } you could simplify to @$foo, but you cannot
simplify what you see to what you said.
Good point! Thats why, IMHO, you should always code in a way that no one
(including you in 6 months) ever has to ask "whats in the world is being
smoked right there' :)
@{ $foo }
@{ $bar{$_} }
@{ $bax->{'tmbg'}[8] }
You always know that whatever is in @{} is supposed to be an array ref ;)
