I personally have never felt the need. One thing I'll often do is a
foreach(sort keys %hash){
#do something...
}
If you know what the keys are going to be ahead of time that might work
for you.

Subject: 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.

Subject: question on Perl determinism with hash keys
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?
