Elvis ?: [enhacement]

[pablogrisafi1975]

Thanks again for your extraordinary work.
You said that adding new operator is difficult because of no extension points at that stage. What about the elvis ?: operator, better known as null coalescing operator ? you know, instead of

String firstName = user == null ? null : user.getFirstName()

i'd like to write

String firstName = user?:getFirstName()

I don't know if that counts as a new operator, since both chars already have a meaning

It doesn't parse, so I'm guessing it cannot be done. But how about a lady gaga operator ?$:?

[pablogrisafi1975]

is that possible? At first I thought it was a joke, but then I saw it as

String firstName = user ? $ : getFirstName() 

And I assume somehow $ is a magical variable that doesn't mess with the type system.

Mi ignorance about the whole source file -> class file process is almost perfect, so I don't know what can be done in each stage.

If it is possible, it is a nice workaround, and while somehow strange, it is way better than

String firstName = user == null ? null : user.getFirstName()

Yes, it should be possible if the $ variable is defined in the background
(the way lombok defines 'val'). However, your last example is the null-safe
dereference operator, which is different from elvis, and is usually ?..
Anyway, I don't know much about the limits of compiler plugins either.
