ETS keys: how complex in usual cases?

[Scott Lystig Fritchie]

Hating to follow up to my own question but ... I forgot to add
something.

In my current (perhaps faulty) thinking, the key format limit hack
would possibly only be required for 'ordered_set' ETS tables.  Do your
typical applications use 'ordered_set' frequently?  ("Correct" ordering of
arbitrary Erlang terms is, er, hard. :-)

I haven't yet experimented enough with the three other flavors of ETS
tables yet; I hope to correct that in the next day or two.
