in order to avoid unnecessary lookups, it should be possible (if not
mandatory) to differentiate avps and pvars syntactically.  it is very
bad, if "$fd" can be either an avp with name "fd" or a pseudo variable
denoting domain of from uri.  in k, "fd" avp would be written as
$avp("fd") and no double lookup would be needed.
