My modified version of RDS' fast_lower() function (used in 'guru.ex' and
'search.ex') also does case conversion at any depth. Yes, it is recursive.

As I wrote, my function (which can also handle special characters such
as the German umlauts) runs in 50% of the time that lower() uses, when
applied to the whole text of Euphoria/Doc/Library.doc.

Do you think my recursive function will be slower than the lower()
library function, when applied to deeply nested objects? I don't
know. I think the library function also will have to do some recursion
internally. And do we apply lower() and upper() more often to deeply
nested objects, or to plain text strings?
