Say I have a list:
l = a, b, c, d
I now want to apply a function, call it F to that list in a way that I go from the lowest to highest level, i.e.
F[F[F[a,b], c] , d]
Is there a function in Mathematica which does exactly that?

This works:
a, b, c, d //. s_?ListQ, t_?(Not@*ListQ) :> f[s], t // f
It's a bit hackish because of the separate invocation of f at the end, but it returns the desired result.
