[erlang-questions] Multi-line comments in Erlang

[Frédéric Trottier-Hébert]

This will only work around a form (function definition, module attribute), and not within it. You won't be able to comment out only a branch of a case, or part of a function definition. Only the whole thing. This makes it less useful when wanting to comment out clauses of an OTP module.

I've found the lack of multiline comments annoying in the past, but most of the time, having the editor (vim in my case) handle it for me has been fine most of the time. It fails at commenting only part of a line when doing very specific tests and debugging, but that's about it.
