I can confirm that, above expression evaluates correctly.

But why does the following doesn't give the correct answer ?

<xsl:variable name="inpValues" select="(1,2,3,4)" as="xs:integer*"/>
fold-left($inpValues, (), function($a, $b) {$a, $a[last()] + $b})

i.e why can't $a[last()] work instead your's ($a[last()], 0)[1]  ?
