Whitespace-sensitive bang patterns (#1087, #17162)wip/whitespace-and-lookahead
This patch implements a part of GHC Proposal #229 that covers five
operators:
* the bang operator (!)
* the tilde operator (~)
* the at operator (@)
* the dollar operator ($)
* the double dollar operator ($$)
Based on surrounding whitespace, these operators are disambiguated into
bang patterns, lazy patterns, strictness annotations, type
applications, splices, and typed splices.
This patch doesn't cover the (-) operator or the -Woperator-whitespace
warning, which are left as future work.
