Module Make.Labels

Operations on Hashtbl with labels.

This module overrides a number of functions of Hashtbl by functions in which some arguments require labels. These labels are there to improve readability and safety and to let you change the order of arguments to functions. In every case, the behavior of the function is identical to that of the corresponding function of Hashtbl.
