But on the other hand we have `javax.script.Invocable`. :-) 

Codespell suggested this change, and I based my decision to keep it based on [Merriam-Webster](https://www.merriam-webster.com/dictionary/invocable) not even listing "invokable" as an alternate spelling, and that "invocable" has about 3x the number of Google hits than "invokable". 

But sure, there is perhaps reason to consider "invokable" an acceptable alternative and keep it. I guess it depends on if you consider the word to be based on "invoke" with a suffix, or a latinized form, like "invocation". 

I'll wait a while for others to chime in, otherwise I'll revert the "invokable" changes.
