Re: retailed (embedded) perl

Try this:

#!/usr/bin/perl

#BEGIN { unshift @INC, sub { warn "loading $_[ 1]\n"; return } } 
#or 
use lib sub {warn "loading $_[ 1]\n"; return };

use CGI;
print "hello\n";


#or 
#Abigail 
#Alternatively, one could just inspect %INC.  
#Just stuff 

#   CHECK {print "$_\n" for keys %INC} 

#somewhere in your code, and run 'perl -c'.

Your is a really interesting solution. I tested both BEGIN { unshift @INC, sub { warn "loading $_ 1\n"; return } } use lib sub {warn "loading $_ 1\n"; return }; and it works, but is not clear to me why sub is executed each time perl scan directories for find an use module can you explain me more aboute this feature ?

In addition to paths, `@INC` can contain code refs (and a couple of other things). When trying to load a module, Perl iterates over `@INC` until the module is loaded. If a path is encountered, Perl looks for the module in that directory. If a code ref is encoutered, Perl calls the code ref with the name of the module to load. The snippet places a code ref at the `@INC`'s head, causing it to be called first. When called, it displays the name of the module Perl is attempting to load. It doesn't load the module, so Perl proceeds with the next entry in `@INC`. References: `@INC`, `require`	[reply] [d/l] [select]
