[Nickle]Type names

[Keith Packard]

Ok, so the current typedef scheme is ugly:

	typedef int foo;
	type foo bar;

Bart proposed:

	typedef int Foo;
	Foo bar;

This reserves every name begining with [A-Z] for typedef names.
That's also ugly.

We could also use

	typedef int _foo;
	_foo bar;

or any other character (except ;,$.()[]{}+-*/%!#^&|~=<>?: )

I don't think we can preserve our current type syntax and usage and get 
arbitrary names as typedefs, the '*' really makes it hard.
