minimize the amount of new syntax where possible

I was wondering what the rationale was for the new instance method syntax [me: Self]. Was there an issue with just passing it in as the first argument, similar as to how it is done is rust? Less syntax to learn FTW.

Great project, c++ has needed a reboot for a very long time.

See p0722 for the rationale behind this choice. Basically, we wanted the contents of the parentheses in a function call to match the contents of the parentheses in the declaration of the function.
