We could use '.'

Then we could use '->' for method invocation.

And '::' for class namespace separators (or whatever they are called).

It shouldn't but I imagine markspace's objection might have been that 
whilst we all learn about the varied uses of '+' at the start of 
learning Java, I expect it can be a little perplexing when you encounter 
a '+' that makes no sense until you find where the original programmer 
defined an overload of that operator. Even worse might be a '+' that 
apparently makes sense but where you do not realise that the operator 
has been overloaded. Is this possible?
