Except that the parameter code has enough fudges holding it together

So that we don't end up with too many typeset flags, this could perhaps
be combined with some facility for ksh93 style lexical scoping. Perhaps
allowing scope to be restricted to within { ... }, do .. done and if
... fi blocks. Another option might be some syntax for in place
functions - some variant of the { ... } block in which local variables
would apply.
