it does. The problem with your suggestion has been discussed many times before 
and it causes breaking dependencies everywhere, which is why it is not allowed 
either and if []; then; fi statements are banned.

You also code in Python style. That's scary. Please learn bash. Lunar is 
entirely coded in bash.

The syntax for optional depends is:

optional_depends "module" "configure flags when selected" "configure flags 
when not selected" "description

The user can choose NOT to install the optional dependency, even if it is 
installed. The user will always be asked about optional dependencies.
