It works fine, but it requires a custom type.

 Hmmm ...  what is wrong with a "custom type", or what I'd call a structure?

It adds code. Unnecessary code.
It is a types added not because they exist in the business domain, but
because there is a need to return a bundle of values.
And the number of possible bundle types is huge.
Multiple return values, generic tuple classes, real tuple etc. avoid
all that.
