I have a strong relationship with PDC that extends over many years. The
common objection regarding the non-standard Prolog type-checking will soon
be put to rest since PDC has plans to permit untyped ISO standard Prolog
programs to run in the compiler, hopefully in their next release (soon).
The results should be a more standard Prolog implementation in which
programs can be typed, as needed, for speed optimization.
