Hi all,
I put in a commit which checks that the special symbol t is not
being used as a pattern variable. Furthermore, the symbol nil
takes on special semantics. It behaves like a variable that is
permanently unbound. Anything that you match with nil is
consumed in the same way like with any other unbound variable,
but it does not generate a binding.
Extract third space-delimited column:
@nil @nil @foo @nil
nil is TXR's /dev/null variable so to speak.
:)
