Clear up zsh - when changing dirs without cd, will check if that will conflict with a command.

#!/bin/zsh
. ~/.zshrc
check_for_collision(){
    is_exec=false
    is_dir=false
    if [ -d $FOO ]; then
        is_dir=true
    fi
    alias $FOO > /dev/null && is_exec=true
    echo "E"$is_exec
    echo "D"$is_dir
    if $is_exec && $is_dir ;then
        echo "Collision!"
    else
        $FOO
}
