Hmm, I have mixed feelings about a warning. In particular, the "proper" way
to handle warnings is to tap into Perl's lexical warnings system, but that
would require a minimum Perl version of 5.10. As it is, though, we don't
really have a well developed PDL warnings system. Throwing a warning might
make sense, but in that case, you should file a feature request that we
finally develop a full PDL warnings system.

Adding integrated PDL warning support would
help a lot with PDL usability.  Imagine:

- niceslice errors reported as niceslice errors

- "spell check" in REPL/pdl2/Padre environments
  [missing sub errors result in completion and
  suggestions for correction...]

- more helpful error messages specific to PDL
  (like use PDL::diagnostics)
