%% Substitution of variables
%%
-%% Dialyzer versions prior to R15B used a dict data structure to map variables
-%% to types. Hans Bolinder suggested the use of lists of Key-Value pairs for
-%% this data structure and measurements showed a non-trivial speedup when using
-%% them for operations within this module (e.g. in t_unify/2). However, there
-%% is code outside erl_types that still passes a dict:dict() in the 2nd argument.
-%% So, for the time being, this module provides a t_subst/2 function for these
-%% external calls and a clone of it (t_subst_kv/2) which is used from all calls
-%% from within this module. This code duplication needs to be eliminated at
