[tlaplus] Function composition operator


Does TLA+ define a function composition operator? I.e., given two functions f and g, can I declare something along those lines:

h == f \function_composition_operator g?


h[x] = f[g[x]] for every x \in the domain of 'g'.

Naturally, the range of function 'g' has to be a subset of the domain of 'f' for this to make sense.
