`CurryApplied`¶

CurryApplied[f, n] is an operator that collects n arguments supplied one at a time and applies f to them in order.

$ wo 'CurryApplied[f, 2][a][b]'
f[a, b]

$ wo 'CurryApplied[Plus, 3][1][2][3]'
6

A list second argument gives an explicit argument permutation.

$ wo 'CurryApplied[f, {2, 1}][a][b]'
f[b, a]
