But wWhat about an anonymous class as ag0aep6g mentioned?
Usability I see is something that is key here. Having to do a
typeof yourself is one extra step away from an intuitive API.
So I tried making a definition like this:
mixin template BitPack( Descriptor instance, string NameAlias =
Descriptor.stringof )
{
mixin( GenerateBitPackBody!( Descriptor, Descriptor.stringof
)() );
}
...but I can't work out how to make the template evaluator treat
descriptor as a templated type without explicitly defining that
type as the first parameter.
Even trying:
mixin template BitPack( alias Descriptor ) if( is( typeof(
Descriptor ) ) )
or:
mixin template BitPack( alias Descriptor ) if( __traits(
compiles, &Descriptor ) )
wasn't getting me valid code (in the case of the latter, it
claims it's not a valid template value argument; in the former,
it meant I would have needed to add additional constraints to the
other BitPack template).
I bet there's a trick out there that'll let me do what I want.
But I won't go looking for it at least.
