Comment (by goldfire):
In the case of a concrete syntax error (as opposed to a type error), I
believe that the location of the error is the first character that fails
to parse. In the case of the original program, that character is the `m`
in the first occurrence of `main`, as reported by GHC. GHC does ''not''
try to find the line where the fix needs to be applied, and I don't think
it should, for parse errors.
