The name “Crystal” is certainly better than “C”, “D” or “Go”. We can search for it. But there are off-topic results. Women named Crystal. Solid state matter, lattice symmetries. Some company named Crystal Group. Quartz crystals in electronics. Another name for glass. Tools of New Age healers.
Apparently, judging from a recent Google search gone awry, there was a little-known programming language named Crystal about 20 or 30 years ago, having something to do with Fortran. Ick!
It’s probably silly to change the name now, and for all I know there have been discussions on that long ago I haven’t seen yet. But I wonder if it’s worth some thought, to pick a word that’s related to Ruby, is nice and easy to say, but not so overloaded in everyday usage.
Among names of gemstones, there are fun and unusual names such as Tanzanite (sounds pretty cool), Tiger’s Eye (brings to mind a strong fast fierce animal), Rhodochrosite (red like ruby, but too long?), Rhodonite (that’s more like it), Rosequartz (red, but “quartz” is taken by other software), and Sunstone.
I know this isn’t going to go anywhere, but it’s fun to contemplate names.
