Re: 'is' and action at a distance

[Michael G Schwern]

Let me see if I understand this...

  $Foo is true;

  # Meanwhile, in another part of the city...

  $Foo = 0;
  print "My spider sense is tingling" if $Foo;

Does that print or not?


I can see the need for wanting to disassociate truth from value (I've
wanted it myself) but if $Foo remains true, even after I've assigned a
false value to it, then yes, that does count as action-at-a-distance
and is probably a Bad Thing.

However, if assigning to $Foo clears the eariler assertion of truth,
then there's no problem.
