It has been many years since I have adopted writing complete programs

Now this has been facilitated even further by providing "let
expressions" in XPath 2.1. I will never have to need to define a
separate xsl:variable whose value is a sequence -- this was not
possible without having let expressions in XPath.

However, I cannot find adequate debugger support for this style of
programming.

Have you considered simply wrapping sub-expressions with trace() since trace() simply returns the first argument as its return value?

The whole program above is treated as one single statement

I tell my students this is a safe way to debug their complex expressions without disturbing the logic of the XPath expression (except for injecting the syntax)

I hope this helps.
