Improve error message when `main' is not of the right type
If you run the following module with GHC(i):
module Main where main = "hi"
You get the error message:
Couldn't match expected type
IO a' against inferred type
[Char]' In the first argument ofGHC.TopHandler.runMainIO', namely
main' When checking the type of the function `main'
The error message would be a bit nicer if the second line was hidden.
