Argument parsing is a mess.

I was inspecting your code to fix the "unreachable code" warning.
But honestly, you should just rewrite this part with std/parseopt

asOptionalParam() used once on a code that ALWAYS quits, so this part of template is completely useless:

        if paramVar.isNone:
          i += 1
        else:
          i += 2
