RE: question on Perl determinism with hash keys

Timothy et al:

Thanks, I did mean in the same order.

Any idea on the relative performance of a hash tied to IxHash vs. a
vanilla hash?

I have a Perl program with many hashes whose entries are created and
destroyed at a high rate, and I'm wondering if I can expect a
performance hit if I make this change...

If you mean in the same order, then no.

All:

If I populate a %hash within a Perl program, is there any guarantee that
from run to run of the same Perl program the keys(%hash) function will
return identical sets of keys?
