XPath expressions into macros,

In XSLT you can already write,

<!DOCTYPE xsl:stylesheet [
  <!ENTITY pattern " '\d{2,5}' ">
  <!ENTITY firstToken "(tokenize(., &pattern;) [1])">
  <xsl:sequence select="//extension ! &firstToken;" />

but syntactic sugar for lambda expressions with arguments and closures,
and the chaining of xsl instructions in the blog post, would be very

  tokenize(., &pattern;) ! λx { if ($x castable as xs:number) then
number($x) else 17 }
