In D1, that's the way you have to do it.
In D2, there is more reflection - I know you can use
__traits(allMembers, Shape) to get the names? Or something like that?
It's completely undocumented, of course. There's also std.typecons
which has an enum generator that will create toString and I think
fromString functions as well.
