- SR-3600 Better recovery for trying to name an initializer, deinitializer, or subscript
Issue Description:
Nothing stops a new coder from writing something like func do something(), especially in Swift Playgrounds where we expect users who have never coded before. We should diagnose this with a nice note like "function names cannot have spaces in them", and offer a fix-it to camel-case the name instead.
(This also applies to types, where this is probably not too difficult, and properties / variables / constants, where it's a bit harder due to how patterns are parsed.)
