Learning Erlang? speedbump thread, common, small problems

Question

I just want know all the small problems that got between you and your final solution when you were new to Erlang.

For example, here are the first speedbumps I had:

Answer 1

• Debugging is hard. All I know to do is to stick calls to "error_logger:info_msg" in my code.
• Docs have been spotty -- they're correct, but very very terse.
• This is my own fault, but: I started coding before I understood eunit, so a lot of my code is harder to test than it should be.
