You are right. It should be mentioned in the help. I will make sure to update the help file with this information.

This is a marvelous feature, that a custom function can call itself, allowing the definition and graphing of iterative and recursive functions. But the 4.3 help file does not appear to even mention this. Ivan, I encourage you to explicitly document this functionality in the help file of the next release.

Stirling numbers of the first kind can be created as a recursive custom function:
s(n,k)=ifseq(n<=k, 1, k<=0, 0, s(n-1,k-1)-(n-1)*s(n-1,k))

I think you can do something similar with Bernoulli numbers.

Can I create Number and Polynomial?

Bernoulli, Stirling, or more.
