The ';' here is for terminating the alias, it is not part of the
delegate.

Basically, the grammar is this:

	alias SYMBOL = DEFINITION ;

It just so happens that DEFINITION here is a function literal:

	delegate ReturnType(...) { ... }

If you substitute this into the grammar, you get:

	alias SYMBOL = delegate ReturnType(...) { ... } ;

That's all there is to it.  This isn't rocket science.
