proc doNothingWith[T](x: T): T = x
let x = doNothingWith((@[], 1))from nim.

Very likely doNothingWith[(seq[empty], int)] used to compile and assigning it to x gave the correct error message. Hence this also used to crash the compiler:
proc doNothingWith[T](x: T): T = x
echo doNothingWith((@[], 1))We can probably add a hasEmpty check to the new finishOperand.
