Hi

For a package which I'm coding I wanna offer to switch on debugging by a constant!

The idea is that the related code is not compiled if the flag is false (codefolding)¹ thus not causing performance lost if in non-debug mode.

Is there any way to tell use constant which namespace to use?

ATM I'm using something like

# --- user's code
package MyPackg; 
use constant DBG => 0;
 
package main;
 
...

MyPackg::func();
 
...
 
# --- my code
package MyPackg;
sub func {
   print "DEBUGGING" if DBG; # won't be compiled
}

Any nicer way to achieve this?

Cheers Rolf

UPDATE: at least it can be simplified for the user with lexically scoped packages: 
{
  package MyPackg; 
  use constant DBG => 0;
}

UPDATE: ¹) better phrased as "unreachable code removal"
