Calling the function doesn't issue any sort of error. Overriding one

Right. And if you're offering a library with UDAs for other people to use?

Which works, but generally makes things more complex in code that's
already pretty deeply nested. It's also something I have to worry about
every

The spec says that a user-defined attribute must be an expression, but DMD

Can you post your full dub.sdl?

It's a bit hard to diagnose the problem you're getting using that
function when we don't have the code that uses it. Or the context that's
