JFYI (but probably you know), MIPS has 2 of them (k0 and k1). These
are part of the GPRs, though, which has the disadvantage that you loose
2 (out of 32) GPRs, but the advantage that you can use them in most
instructions.

when I'm talking to journalists I just say "programmer" or something like that.
