Not sure what's going on here...

The error code the program returns appears to always be 0, even in the case of fault. An example session:

╰─➤  mdlt 'x' 'x'
Improper format.

Usage:
mdlt [operation] [expression]
OR
mdlt [operation] "[expression]"

╰─➤  echo $?
0

Which is making it quite difficult to automatically tell when it fails... ^.^;
