Replicated the pseudo-hash mis-error statement...

[dragonchild]

After thinking through the situation, it turns out that this is the exact model for what I was doing in the larger script. Note the re-definition of $sortfunc.

Now, yes I know that there's a definite package-scoping problem, but I'm posting this to see if this is actually a potential problem with the 5.6.0 interpreter and pseudohashes that might come out in other situations, not just one where the programmer (me) is making a scoping error.
