By the way, why does it try to evaluate tests even with --doc-only?

Mathics version: 1.1.1

@suhr you are the best person to find and fix such problems. Would you just make the changes that need changing?

As to why it executes the test, I am guessing that in the doc it want's to show what the output woudl be.

I think this was fixed in #1163. @suhr, could you confirm it?

[rocky]

Assuming this is fixed.
