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.
