I've used Calca[0] for a while now; and it computes pretty much anything I throw at it. And while its paradigm is nice for a lot of things (a markdown editor that can also do math), I would love a REPL-style interface to it, for quick commandline calculations, so maybe this will fill that void. However, my initial reaction is that its different enough to make it not worth my while. But it's always good to see other products/tools in the same space.
Oddly enough, the reason I eventually stumbled Calca was trying to find a replacement for qalculate[1].
