What about matching?
M = #{1 => 2}.
#{1 => 2}
143> #{1 := V} = M.
#{1 => 2}
144> V.
2
What about reading the manual? :-)
<http://erlang.org/doc/reference_manual/expressions.html#map_expressions>
Similarly:
%% Instead of Val = Record#rec_name.some_field.
#rec_name{some_field = Val} = Record.
Lest Erlang turns into Java ;-)
