A+B

This actually looks horribly complex for a+b program. FIXME: won't exit because printlns won't exit

How can we improve it?

This logic sig -> readln -> parsein -> [print err] -> int could be moved into separated component. Alternative is to return also err. Like this: sig -> (readlin -> parseint) -> [int, err]) into readlnInt`
