Oh, I see what you're getting at. I missed the signature on first read. So you're saying that would generate a callable equivalent to: $fnMethod = fn (Zok $zok, string $zebranky): Frungy => $zok->Pik($zebranky); That's an interesting idea, though probably not self-evident to many people. If we wanted to do that, I'd probably push for something more compact as a syntax, and a bit more auto-refactorable. I think the Ara language had syntax for something like this, $$->Pik(...) ? If I'm remembering correctly, which I may or may not be?
