God bless you, oh Monks!

I am meditating on the following not so complex only at first glance piece of code:

(caller)[1] eq $0

[download]

Is this always true within single perl script file?

It is very interesting to see the implementation in Perl source code of the following things:

1) internal function caller()

2) variable $0

So can you please give a guidance where to look in Perl source for them?
