G'day hv,

++ Thanks for your response.

I originally just tried to import it. My code crashed at that point; like this:

$ perle 'use Judy::HS "MemUsed"';
"MemUsed" is not exported by the Judy::HS module at /home/ken/perl5/pe
+rlbrew/perls/perl-5.36.0/lib/site_perl/5.36.0/Sub/Exporter.pm line 77

I basically took the documentation at face value and assumed that I needed something in addition to libJudy. However, I now see that a fully-qualified name will access it:

$ perle 'use Judy::HS "Set"; my $judy; Set($judy, Key => 42); say Judy
+::HS::MemUsed($judy);'

"I took a brief look at the code, and it looks buggy ... If you're happy to run a patched version, I can provide a one-line fix for the obviously buggy case."

I've just been tinkering with it; comparing $judy with %hash. I've written some basic benchmarks to test speed; I looked into some of the Unicode issues raised in Judy::Mem; and was planning to do a size comparison as well. Depending on how all of that panned out, I had some tentative thoughts on other aspects to investigate.

Some of my $work involves biological data which, as I'm sure you're aware, can be huge and require long processing times. I'm always on the lookout for more bang-for-your-buck in this area. Having said that, given your comment that "it looks buggy", and the fact that it appears to be abandonware, I'm wondering if this is worth pursuing. In light of that, while I very much appreciate your offer of supplying a patch, I think I need to give some serious consideration as to whether I'll continue with Judy & Co. before taking you up on that.
