Why not add list support to erlson

[gemSender]

for example:
D = [{name, <<"joe">>}, {friends, [<<"jack">>, <<"peter">>]}],
D1 = D#{friends.1 = <<"john">>},
D1 = [{name, <<"joe">>}, {friends, [<<"jack">>, <<"john">>]}].

Well... Next thing you realize is that you want to also index by an arbitrary integer expression, e.g. being able to do something like D#{friends.[Expr] = <<"john">>}. Or firends.[Expr] in general. Essentially, this is similar to what another person suggested in #12 Please see my comments there.
