Hi Monks,

In the script below, the lexical variable $lost is not visible to &test_sub2 which is what I expected. But I wonder why lexical variable $tricky is visible to &test_sub? How does Perl treat the lexical variables defined in the main script differently from those defined in a block?

Thanks in advance :-)

#!/usr/bin/perl
my $tricky = "in main";
&test_sub;

sub test_sub {
        print "$tricky\n";
        my $lost = "gone";
        &test_sub2;
}

sub test_sub2 {
        print "$lost\n";
}

The script above prints "in main".
