I don’t know why “repeat” isn’t very common in place of while/loop/etc; it works out nicely grammatically.

    repeat {}
    repeat while <condition> {}
    repeat {} while <condition>
    repeat <count> {}

One possible reason:

> The word "REPEAT" should not be used in place of "SAY AGAIN", especially in the vicinity of naval or other firing ranges, as "REPEAT" is an artillery proword defined in ACP 125 U.S. Supp-2(A) with the wholly different meaning of "request for the same volume of fire to be fired again with or without corrections or changes" (e.g., at the same coordinates as the previous round).

More seriously, PASCAL has repeat-until loops, similar to do-while loops in C.

Pretty C does aliases "repeat" for "do", so yeah, I've got you covered!
