Which domain would this DSL be specific to?

  As in less general than recursive functions. But I admit it's a very subjective point.

    Personally, I feel the "recursion is the only way to iterate" purity is practically harmful, even though it is quite elegant for theory. K/J/Q/APL2 and friends[0] have isolated iterative constructs that cover IME 98% of what's needed (each, fold, scan, fixed point, ...) in a way that's just as simple to analyze as recursion[1]. These languages do like DSLish for the first 10 or 20 examples you see - but by the 200th example, it is clear the domain it is specific to is "mostly everything" [0] I'm not considering APL1 as part of the modern family - it had Fortran-style computed gotos for control flow. [1] Although there's about 10 times as many of them, so it's not quite as elegant.
