[texhax] Enumerate with Roman numerals?

[Robin Fairbairns]

> I would like to use a top-level enumeration with Roman numerals (I, II, III,
> etc.). However, my attempts to use renewcommand to redefine \theenumi have
> been unsuccessful. Specifically, the redefinition is being interpreted as a
> literal string and not as commands to execute.
