Description

currently, type alias definitions support a refactoring to "inline" the type alias to all uses, deleting the type alias in the process.

i would like the reverse: a refactor on a type alias so that the type alias is substituted everywhere possible.

obviously "everywhere" is a little unclear, but at least to all locations in the current module would be plenty useful.

Research direction

Start by locating the existing type-alias "inline" refactoring and trace its entry point and tests. Compare that behavior with the requested reverse operation, then define which alias uses in the current module are supported. Done means the refactoring substitutes the alias at all agreed supported locations and has coverage for those cases.
