[erlang-questions] [clarify] Variable binding in case clause and coding style

[Dmitri Girenko]

Hi all,

I have a question about variable binding inside the case clause, that I
sometimes use to simplify some code like this:

case Endianness of
  big-> <<A:1/unit:32-big, Rest/binary>>;
  little-> <<A:1/unit:32-little, Rest/binary>>
end,
do_something(A,Rest).

But this seems to be a kind of... hack. I wonder what problems can this
coding style cause? Can there be any problems with parse
transformations? With refactoring tools?
