Re: "return" behaves differently in .zlogout (Was: Subshell return codes are discarded during logout?)

Is this intentional?  Seems like a needless discrepancy.

It's intentional and you can see why if you do this:

outer% ZDOTDIR=/tmp/workers-53281 PS1='inner%% ' zsh -l
inner% exit 14

reached

outer% print $?

14

That is, "return" does not clobber the exit status specified for the top-level shell, whereas a subsequent explicit "exit" does so.
