Although I say it myself, I think the xsl:iterate instruction in XSLT 3.0,
which is essentially syntactic sugar over a fold operation, addresses the
readability problem quite well:
> $newKeys => fold-left($m1, function($key, $map) { $map => map:put($key,

becomes
<xsl:iterate select=“$newKeys”>
<xsl:param name=“map” select=“$m1”/>
<xsl:on-completion select=“$map”/>
<xsl:next-iteration>
<xsl:with-param name=“map” select=“map:put($map, ., ($map(.), $obj))”/>
</xsl:next-iteration>
</xsl:iterate>
