I've been trying out a weak pretty-printer for Erlang.
(By "weak" I mean that it takes care of indentation but
does not do anything about line breaking.) It's supposed
to be something I can build into my text editor.
When I tried feeding other people's Erlang code into it,
I ran into some problems.
I was aware that when you write
the stuff in RHS did not have to be bracket balanced, so
What I was *not* aware of was that there doesn't even have
to be a closing right parenthesis at all.
ick() -> ?ICK.
The Erlang compiler is perfectly happy with this.
There are several occurrences of this in the Erlang/OTP sources,
but there doesn't seem to be any reason why.
