in reply to Which subroutine or method was called?

OR, you could use CORE to call bulitin like so: 

  use strict;
  use warnings;
  use Time::HiRes qw(); # just like others said

  Time::HiRes::sleep(2);  # module sleep function
  CORE::sleep(2); # bulitin sleep function

[download]
Then to see what went down call your script like so perl -MO=Deparse perlscript.plthen you see this: 
use Time::HiRes ();
use warnings;
use strict 'refs';
&Time::HiRes::sleep(2);
sleep 2;

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
