I finally decided to get off my behind and submit Games::Dice to the PAUSE. I was rather shamed when I saw that the files were dated April 1999... they've been sitting around my hard drive here at work for a long time. But I decided it was probably best to "release early, release often" so I cast it loose. And as I remember the docs were fairly decent and the module worked last time I touched it. It doesn't have any tests beyond the one h2xs gives you, though (but testing random things is a tad difficult, anyway).
It used to be that I had one module on the Module List but not on CPAN and several on CPAN but not on the Module List... well, now my Module List module is also on CPAN. I uploaded v0.02 the next day after minor tweaking (changing my email address and adding a licence); v0.01 will probably go away again. I do wish that I got some reaction to my request for registering the other modules. email@example.com appears to be a black hole at times... but that's another story.
I also had a go at implementing yEnc. For that module, I really did "release early, release often": v0.01 of Convert::yEnc had no decoding, v0.02 had no prerequisites listed in Makefile.PL and v0.03 still has no decent docs or tests. But at least it compiles! Maybe I'll get around to working on it some more later.
I'm also wondering whether there are any modules dealing with "metric time" (100 seconds to the minute, 100 minutes to the hour, 10 hours to the day) or with the 28-hour day (which you can read about in a couple of places on the web; briefly, it divides the week into 6*28 hours rather than 7*24). A quick glance at search.cpan.org didn't unearth anything likely.
