Use `rec` so functions can refer to themselves in their bodies. Code like the following kind is legal in Python: ```python def recursive(a): return recursive ``` This implies that function and class definitions need to use the Core `rec` construct so that their bodies have an appropriate entry in the scope. 2019-10-17 00:34:43 +03:00			`# CHECK-TREE: { Foo <- rec Foo = { identity <- rec identity = \self -> \x -> x; __semantic_prelude.type "Foo" __semantic_prelude.object #record { identity: identity } }; #record { Foo: Foo } }`
