2013-12-12	EEP 37: Funs with names	Anthony Ramine
	This adds optional names to fun expressions. A named fun expression is parsed as a tuple `{named_fun,Loc,Name,Clauses}` in erl_parse. If a fun expression has a name, it must be present and be the same in every of its clauses. The function name shadows the environment of the expression shadowing the environment and it is shadowed by the environment of the clauses' arguments. An unused function name triggers a warning unless it is prefixed by _, just as every variable. Variable _ is allowed as a function name. It is not an error to put a named function in a record field default value. When transforming to Core Erlang, the named fun Fun is changed into the following expression: letrec 'Fun'/Arity = fun (Args) -> let <Fun> = 'Fun'/Arity in Case in 'Fun'/Arity where Args is the list of arguments of 'Fun'/Arity and Case the Core Erlang expression corresponding to the clauses of Fun. This transformation allows us to entirely skip any k_var to k_local transformation in the fun's clauses bodies.

2011-09-08	ms_transform: Fix incorrect `variable shadowed' warnings	Haitao Li
	Compile below module resulting incorrect warning: $ cat tmp.erl -module(tmp). -export([tmp/1]). -include_lib("stdlib/include/ms_transform.hrl"). tmp(X) when X > 100 -> Y=X, Y; tmp(X) -> ets:fun2ms(fun(Y) -> {X, Y} end). $ erlc tmp.erl ./tmp.erl:8: Warning: variable 'Y' shadowed in ms_transform fun head The scope for a variable is its function clause. Variables bound in one function clause should not interfere with other function clauses. This patch removes incorrect passing of variable bindings from one function clause to another.
