Eh, this is just a try to make something work that uses rules which are lesser sophisticated than the shell is, and which cannot (yet) offer simple variable assignments which (at least potentially) involve macros/functions or even subprocesses, as in x=`quote bla`. It is a bit of a crux. But getting better. (Never supporting redirection i thought, as can be seen above, though, never being a real shell. But a bit.)
