Fair enough.

Feels like a DIHWIDT to me. If you want to override these special methods in
your class, it's your job to ensure they return the correct expected type.
The error isn't terrible and is correct and improving it would likely require
pessimising one of the most oft-used routines.

Returning a Str from a custom class's .gist works fine:
➜ class A { method gist { "42" } }; say A.new;
42
But when returning other values, it fails to convert them to Str
automatically, and instead prints an internal-ish error message:
➜ class A { method gist { now } }; say A.new;
This type cannot unbox to a native string: P6opaque, Instant
in block at -e line 1
➜ class A { method gist { 42 } }; say A.new;
This type cannot unbox to a native string: P6opaque, Int
in block at -e line 1
