File::Find and $_ in nested subroutines.
- by zedoo
When running the following code, the filenames of all files below C:\Test are printed. Why doesn't it print just Hello (n times, depending on how many files are processed)?
Does this imply that I cannot rely on shift to reliably assign to $_? Imagine a coworker implements the wtf function and doesn't know that it's called from a File::Find wanted sub.
I run this code with Strawberry Perl 5.12
use strict;
use warnings;
use File::Find;
find(\&wanted, "C:\\test");
sub wanted{
wtf("Hello");
}
sub wtf {
shift;
print; #expecting Hello
}
