I agree that there ought to be a user-readable version number available

I'm not crazy about the name either, but I couldn't think of anything better.
My other choice was "i
Here's a patch to have the vocab loader save Factor's initial current directory
at startup time and use it as the base for relative vocab roots such as ".".
That way, the program changing the current directory as part of its normal
operation won't affect the vocab loader.

In your "main" you missed the [ ] around prop-even. This line:

The generators needn't be in an array; they could be a simple quotation. Simply
calling each generator function in turn will line up their outputs on the stack

Asking for a function that pushes all the elements of an arbitrary sequence

It looks like arguments after the script name aren't ignored, but put into a
