[erlang-questions] Comparing terms == vs. =:=

[Ricardo Catalinas Jiménez]

I have read here http://erlang.org/pipermail/erlang-patches/2012-March/002721.html:
"It is always better to use =:= instead of == when not comparing numbers"

So, apart from prevent an implicit integer cast to float in the
comparison:

1> 1 =:= 1.0.
false

What is the purpose of using =:= with all kind of terms?
Better performance?
