Issue Description:
func switch() { }
repl.swift:1:6: error: expected identifier in function declaration
func switch() { }
^
We can do better than this. Someone inside Apple suggested "keyword 'switch' found where an identifier should be in a function's name. Try picking a different name for the function or putting backticks (`) around the name." The suggested fixes (the second sentence) should probably be two separate notes rather than crammed into the main diagnostic.
