I thought I could make this work, but it's a problem. There are two
meanings for scope when attached to a function:

     T func() scope;   // the 'this' pointer is 'scope'

T func() scope(this);

or:

T func(scope(this), ARGS);

It is theoretically the first argument after all.

     scope T func();   // the function returns a 'scope' T

I have some ideas, but don't particularly like any of them. But I don't
want to bias things, so what ideas do you guys have?
