'up.' is an internal function implemented in directly in Java. It was
needed as a functional equivalent to 'up' because I needed something
that would expect quoted agruments. 'up' is not programmable.
// (up [cnt] sym ['val]) -> any
// (up. ['cnt] 'sym ['val]) -> any
I gave it the ugly name 'up.' to indicate that it is internal and not to
be used in application code.
