 ## Motivation  
 
-The purpose of this feature is to dvelop syntax to prevent polymorphic types from widening into (e.g., number | string) when a function is implicitly instantiated with different argument types. E.g., `test(1, "a")`. In the following code, Luau's current solver infers `T` to be of a union type:
