in reply to CPAN and readline on windows
Well, given that so much of CPAN.pm is still based on globals, you can do this:
perl -MCPAN -e "$CPAN::Suppress_readline=1; shell"
Eventually, that should probably get moved to (yet another) configuration option. Please consider opening up an RT ticket about it if there isn't one already so we have it on the list of things to do.
