Thanks, that's really helpful to read! The page is still in a very early stage. You are right, the current object section is just confusing, we will remove it.

Maybe a better start to understand what Wikifunctions does - but it is a very simple example too - is this function: https://www.wikifunctions.org/wiki/Z10000

The other functions that you found randomly are currently not well supported.

We are working on it, to make it less confusing. Such feedback is very helpful.
