I have not the foggiest idea what you are talking about, the
use of this attribute in the patterns implementation has very
little to do with downward closures. If you think you could
replace the usage there with formal subprograms, you are welcome
to try (it would be nice because they nyou could use this
package on the Rational compiler for example).
But I can't explain to you why I can't do something that I
don't even begin to see could be done :-)
