I don't think we're disagreeing on the use of $! only after a failure (i.e. only after a check of the result from readline for definedness).

However, it's critical that $! be "emptied" (set to a FALSE value) before calling readline, if $! is to be used to distinguish between EOF and a read error, as the code from perldoc readline does.
