Chris -

The cynic in me would argue that this would be a non-issue with stricter
namespacing, but I suppose that in the end one would have imported this
method and run into the same problem even with stricter namespacing.

I think your idea makes sense, but I fear there is little we can do about
it now. User code might depend on the result being a piddle. Perhaps we
could implement this for PDL3, the non-backwards-compatible version of PDL
that rocks the numerical community's world slated to come out Christmas (of
some uspecified year). :-D
