Parse errors for mismatched brackets are awful
ghci> [foo
<interactive>:1:4: parse error (possibly incorrect indentation)
The parser error messages for incorrect brackets are awful. A much better message would be:
ghci> [foo
<interative>:1:1: bracket opened but not shut
i.e. refer to bracket issues, and say where the bracket started.
I realise this may be difficult within the current parser, but a simple post-processor for syntax errors could perhaps detect such errors. Also, while the { character and reasonably be about indentation, the others are much less likely to be.
