Template accepting code blocks as a parameter.

[Andrew Fedoniouk]

Let's say I'll be able to define mixin template which
is able to accept block of code (aka closure) as a parameter.

So if I declare something like this:

template on_scope_exit(B: void delegate() )
{
    auto ScopeGuard sc#__LINE__ = new ScopeGuard(B);
}

then I would like to be able to write something like this

mixin on_scope_exit! {  delete foo;  }

Which will expand to something like this at the point of mixin:

auto ScopeGuard sc1234 = new ScopeGuard( { delete foo; } );

This is just a rough idea.

Having this will allow to define onScope*** in the way that task needs
and I beleive it will be useful in other places too.
