All of the FXSL functions are such examples.

As for new functions, my recent Medium articles may give us an idea:


   - "Generators in Xpath",
   https://medium.com/@dimitrenovatchev/generators-in-xpath-987a609cfbd5,
   and friendly link for non-members of Medium.com:

   - "Laziness in XPath. The trouble with fn:fold-right",
   https://medium.com/@dimitrenovatchev/laziness-in-xpath-the-trouble-with-fn
-fold-right-cbb1cc654d1c,

-fold-right-cbb1cc654d1c?sk=872244cf80bfcb52d67bcb8b359478ff

Other functions/features that I have proposed for inclusion in XPath 4 are:

   - Decorators, https://github.com/qt4cg/qtspecs/issues/106
   - Sets, https://github.com/qt4cg/qtspecs/issues/34
   - Extending maps to allow as keys not only atomic values, thus making
   possible implementing sets and caching of function-calls results,
   https://github.com/qt4cg/qtspecs/issues/119

These may or maynot be included in XPath 4 (and the Functions and Operators
standard specification), and if they don't get included there, these would
be the primary candidates to be provided in a 3-rd party library.

More generally, as I said before, any established and used in best
practices Design Pattern.

Thanks,
Dimitre.
