💻 Code

// EXAMPLE

declare function create<T extends 'foo' | 'bar'>(value: T): T;

declare function a<T>(value: T): T;
declare function b<T>(value: T): T;

// autocomplete works
create(a('foo'));

// autocomplete doesn't work
create(a(b('foo')));

// PARTIAL WORKAROUND

type NoInfer<T> = T extends infer U ? U : never;

declare function a2<T>(value: NoInfer<T>): T;

// autocomplete works but type becomes unknown
create(a2(b('foo')));

🙁 Actual behavior

When functions are nested the types flow through and are checked correctly but autocomplete doesn't provide suggestions.

🙂 Expected behavior

I would like autocomplete to provide suggestions for arguments in nested functions, based on the underlying return type. My actual use case involves more complex functions that are used to build nested objects.
