Well the unary operator '%' is programmed to become "classalloca( )",
so you can write "classalloca( std::async( EntryPoint ) )" instead of
"%std::async(EntryPoint)".

I think the unary operator is cool for this though. Like how
structured bindings didn't add any functionality at all to the
language but were just deemed cool enough to make it in.
