Hello monks!

I'm having some trouble with referencing local variables. Simplified example:

$a=3;
{
    my $a=5;
    say ${a};
    say ${'a'};
}

Prints:

5
3

What is this madness, and how do I make it stop?

The typical case where I want to use it is when I have a handful of arrays and want to do stuff with each of them, like so:

@cat=(1,2,3);
@dog=(5,6);
@pig=(4,3,2,1);
for('cat','dog','pig'){
stuff(@$_);
}

which works fine as long as the arrays are global, but if they're local, it doesn't work. How can I reference the local ones?
