Cannot call value of non-function type 'module<Commander>'

[yeldarby]

I'm getting an error after installing and importing Commander via Swift Package Manager:

import Commander
Commander().dispatch() // <-- Cannot call value of non-function type 'module<Commander>'

Desktop (please complete the following information):

• OS: macOS 10.15
• Xcode: 11.1

Additional context
Calling Commander.dispatch() instead seems to work but no Options or arguments get passed to my commands. (I got this working by implementing init(from decoder:Decoder) -- that should probably be added to the docs.)
