Node sets are already boxed so the translation is just a NOP.

type. The translation to int is undefined
since node-sets are always converted to
reals in arithmetic expressions.

The boolean value of a node-set is "true" if non-empty
and "false" otherwise. Notice that the
function getFirstNode() is called in translateToDesynthesized().

value of its first element.

push a 0 or a 1 but instead returns branchhandle list to be appended
to the false list.
