A safe `rm' for bash

I have many times typed
rm -rf *  !!
in a hurry, unknowingly
This can be really really upsetting, depending on which directory you
are in ! :)
While talking to my teammates on how to make rm a little safe, I
tried the following:
alias rm to a function, which will check the args and then force
interactive mode. The option check is simple, the only problem is
your function will not receive '*', as the shell would have already
expanded it!
The solution is to club alias and function, with disable globbing
and then re-enable it!

Thanks to Simon's article which helped me with this.

Full bash function here:

alias rm='set -f;rm_in'

rm_in() {

    local YN HIT LAST N

    N=$#

    LAST=${!N}

    if [[ $1 =~ -[fr]+ ]] && [[ $2 == '*' ]] ; then

        HIT=1

        echo -n "Are you insane ? (y/n): "

        read YN

    fi

    if [[ -z $HIT ]] ; then

        if [[ $LAST == '*' ]]; then

            HIT=1

            echo -n "This is li'll scary, are you sure ? (y/n): "

            read YN

        fi

    fi

    set +f

    if [[ ! -z $YN ]]; then

        if [[ $YN =~ [yY] ]] ; then

            echo "May it be! .."

            eval command rm "$@"

        else

            echo "Thank God!"

        fi

    fi

    if [[ -z $HIT ]] ; then

        eval command rm "$@"

    fi

}
