For me itbs probably maps, as it allows structured results. Iterate helps a
lot in some cases (e.g. processing static variables in an XSLT compiler ;-)).

Dark horses might be accumulators (though I admit to never having used keys in
2.0) which are slowly growing on me.

And without xsl:evaluate an XSLT compiler in XSLT would be considerably more
complex. I should also of course use packaging .... real soon now....
