I know, but you can use it as a function.

Yes, I don't believe this is ever claimed in the docs.

comment Assumptions aren't working in this sum
@MichaelE2 Thanks, do know you why the Assumptions need to be put in two places? because the inner assumption seems to do nothing Assuming[\[Alpha] > 0 && \[Beta] > 0, FullSimplify@ ComplexExpand[ FullSimplify@Sum[1/(\[Alpha] n^4 + \[Beta]), {n, 1, \[Infinity]}], TargetFunctions -> {Re, Im}]]

comment Assumptions aren't working in this sum
I added the assumptions that alpha and beta are Real. So the sum should be real, but the result contains complex numbers: (-1)^4 or (1 + I) / Sqrt[2].

What it f relied on a function g which relied on a function h in package i?

Sorry it's spring and I have plants on my mind... I'll add a concrete example.

comment How to compute scores with a ClassifierFunction's SVM?
One motivation here is that if one can understand how mma computes the prediction then you can successfully export the svms generated by Classify.
