This could lead to different behaviour if the argument contains non-numeric characters, or if the argument has leading zeroes and the OCTAL_ZEROES option is set. +3) For some time the shell has had a POSIX_TRAPS option which determines +whether the EXIT trap has POSIX behaviour (the trap is only run at shell +exit) or traditional zsh behaviour (the trap is run once and discarded +when the enclosing fuction or shell exits, whichever happens first). +The use of this option has now been made "sticky" on the EXIT trap --- +in other words, the setting of the option at the point where the trap is +set now determines whether the trap has POSIX or traditional zsh +behaviour.
