Ah, lol. I guess there's some merit in checking if it actually compiles and in reading the rest of a function body ^^.

The default_value naming is pretty misleading, it looks like it only returns something for constant parameters (because only they has values).
I thought the GenericParamDefKind::Type was lost here before I looked at the definition.

How do you feel about renaming it to default?

Alternatively, default_term (cc, {ast, hir}::Term) or default_arg?

I think default_term would be fine and probably actually an improvement, but also I don't know if I share the same concern about the default_value name.
