Flip-flop. Flippity-flop goes my braine.

I've decided not to change the behavior of UNIVERSAL::require. Why?

1) Jesse's suggestion of using $@ instead of $UNIVERSAL::require::ERROR. It makes the error checking code much less disgusting to type.

2) The existing behavior has survived four years without anyone hating it enough to file a bug or patch.

3) Its such a simple module its not worth the turmoil.

I thought that would work anyway... (Score:2)

I always used "$foo->require or die $@". Now it'll actually be the right thing! See, pick the interface that your users would use naturally...

Like add a require_or_die method?

  I've thought about that. It seems silly given my reasons for wanting to make it die.
  
  1) People would write $module->require without realizing it wouldn't die on error.
  
  Well, require_or_die() doesn't help with that. If they don't think $module->require doesn't die they'll probably never notice require_or_die().
  
  2) $module->require or die $UNIVERSAL::require::ERROR is nasty.
  
  $module->require or die $@ is nearly as short as $module->require_or_die
  
  So not really worth it.

    How about an option when you use the module:
    use UNIVERSAL::require qw/fatal/; SomeModule->require; # blows up
    ?

      Already covered why that won't work. [perl.org]
