It's not so much the output as the input. I hope REPL would wait for more.
The compiler allows empty indentation:
def f = List(42).foreach:
end f
// package may not be empty, class template may be empty
package p:
class C:
end C
end pExpectation
The def f with empty indentation requires either end f or eof. Expect it to require a block expr and not happily eta-expand.
In REPL, it should work like class C:.
Spec requires a touch-up for the ArgExpr, but feature is still behind a flag.
