Re^3: Manipulate deepest values in complex hash structures

[pachydermic]

Great post, LanX. I have two questions:

For the line:

$type //= "SCALAR";

am I correct in thinking that this is using the or operator as you would like += or .=? So that $type takes the value "SCALAR" if it doesn't already have a value? I looked in perlop, but I wasn't aware you could use logical operators like that...

My second question is how

$code->($_[0]);

performs the operation on $_[0]. Currently I'm trying to become more comfortable with references (and they're very confusing), so I'd appreciate it if you could point me in the correct direction. I've already read http://perldoc.perl.org/perlreftut.html, but I'm trying to make it stick now.

Thanks in advance!
