Howdy List!
I noticed in the source code for the File::Slurp module that it does 'use strict;' and then in sub error {} it calls a function like so :
$func->($err_msg);
I was curious as to how that is possible without using "no strict 'subs';" or "refs" or something , and have it not cause an error of some kind?
In this case, $func holds a "hard reference", not a "soft reference". The strict pragma only blocks the latter.
Here's a simple example:
sub howdy { print "Howdy!\n"; }
my $func = \&howdy; # hard reference $func->(); # fine, even with strictures
$func = 'howdy'; # soft reference, name only $func->(); # will not pass strictures
Hope that helps.
