[ic] more questions on PERL variables

[Zachary Matthews]

I'm also wondering if anyone knows, when I set a variable with a [perl] 
tag, how is this variable later accessable?

For example, if I say:

[perl]
    $Scratch->{foo} = 'bar';
[/perl]

I can later access this variable with:
[scratch foo]


But when I do:

[perl]
    $foo = 'bar';
[/perl]

How do I access this value outside of the [perl] tag?

Thanks again,
Zac
