UDA's can not permute the type, so I guess it's impossible to
implement
something like @noalloc that behaves like @nothrow in a
library...
I wonder what it would take, it would be generally interesting
to move some
of the built-in attributes to UDA's if the system is rich
enough to express
it.
Both blessing and curse of UDA's is that they are not part of
type and thus mangling. I think it is possible to provide library
implementation of @nogc for cases when all source code is
available, but for external libraries and separate compilation it
will become matter of trust which is hardly good.
