Same for imperative languages with "parameter list" style.
In python, with
def f(a, b): return c, d
def g(k, l): return m, n
you can't do
f(g(1,2))
but have to use
f(*g(1,2))
what is analogical to uncurry, but operate on value rather than function.
TBH I can't name a language where such f(g(1,2)) would work.
- shawn_w 7mo agoperl, though that uses lists rather than multiple value or fixed-size tuples: #!/usr/bin/env perl use v5.36; sub f($a, $b) { return ($a+1, $b+1); } sub g($k, $l) { return ($k+1, $l+1); } say for f(g(1,2)); prints out 3 4
