   <xsl:variable name="x" select="my:foo(bar)" as="appropriate type"/>


   <xsl:variable name="x">
        <xsl:sequence select="my:foo(bar)"/>

The first of the two above is shorter and probably stylistically better.

It is not "semi pull style". Its pull style when only one template has
that mode or matches a node from a uniquely defined namespace (used
only for the purpose of identifying its matching template).

Sure, like when beating a dead horse.

Hey, where did I say that you were "entirely wrong" or just "wrong" ?
