Oh, I see what you mean.  I was taking for granted that y was evaluated properly and was passed into 13!:19 as an argument.  If then y is invalid, 13!:19 gives an error and performs no action.

I didn't understand what Raul meant by 'detected too late' and made my best guess.

Yes, but this

   No, y is ignored, except when it produces an error.

reads like y may produce an error /inside/ rather than before.
As if y would not be evaluated (and maybe throw) outside.

I’d expect that actually y isn’t ignored in that case
but the call doesn’t occur at all because the error comes first.

13!:19 ] 1

is just a domain error, on that line.  No action is performed.

if I understand correctly, you are telling me that currently the error
is detected too late?
