-=== EXTRA NOTE ===
-All blocks are scoped, including variable definition and environment variable changes.

-Because of this, the following doesn't work:
-
-def-env cd_with_fallback [arg = ""] {

-    if $arg != "" {
-        cd $arg

-
-def-env cd_with_fallback [arg = ""] {
-    let fall_back_path = "/tmp"
