That means the function body has to be provided as a string argument. This tends to cause some seriously unreadable code. It may be a lost cause but I'm hoping we can amend the language to avoid that.

Also, vibe.d internal `cloneFunction` which generates copy of method/function signature with fully qualified type names (for mixin hygiene): https://github.com/rejectedsoftware/vibe.d/blob/master/source/vibe/internal/meta/codegen.d#L177
