Dear Monks,

Is there any way to know if my sub was called in a "numerical" context or a "string" context? 

use strict;

sub sensible {
  return "one" if stringcontext();
  return 1 if numericalcontext();
  return;
}

print "Result = ".sensible()."\n";   # Result = one
print "Result = ".0+sensible()."\n"; # Result = 1

A partial solution is to use dualvar from Scalar::Util but then I have to compute both the string and the number on each call.

Many thanks

Casiano
