Re: chomp it chomp it good

It uses Magic.

If you check the perl source, you'll see that it is implemented as Perl_do_chomp in doop.c and it takes a pointer to an SV (which is fed to it from the top of the stack down since chomp can take multiple arguments) and that pointer is the C equivalent of a reference.

St. Larry be praised, there is much magic to make our lives easier in Perl.

It will be great if you can post the code snippet of the c code..

Here's an analogy:

my $bar = 41;
foo($bar);
print $bar;

use Inline C => <<'EOC';
void foo(SV* bar) {
   int b = (int)SvIV(bar);
   b++;
   sv_setiv(bar,b);
}
EOC
