Using `Self` when initializing a tuple struct

[U007D]

https://internals.rust-lang.org/t/initialization-syntax-for-self-tuple-structs/5389/5 talks about this problem. But the solution (using the typename, rather than Self) isn't discussed anywhere (that I could find).

Could a helpful compiler message be added (until the problem is fixed)? Something to the effect of
"Use of Self when initializing a tuple struct is not currently supported. Please try <typename>(...) instead." (where code following 'Please try' is the user's code with Self replaced with the struct's typename).
