Lexer: Suggest adding 'let' on unexpected '=' token
Summary:
I've heard numerous fledgling Haskeller's complain about the behavior of
ghci regarding bindings. While most REPLs accept bindings of the form
`x = 42`, GHCi is implicitly a `do` block, meaning that the user must
know to use a `let` to introduce a binding.
Here we suggest to the user that they may need a `let` and give them a
small example in the event that we find an unexpected `=` token.
