I hope I didn't give the impression that I was casting aspersions on
Dyalog. They've taken APL in some new and interesting directions. All I
meant is that many of Dyalog's contributions to the language tend to be
outside of the canon of ISO/IBM APL 2.

As I envisioned it: the former. Just some syntactic sugaring around an
APL function.

Its used to provide access to many of their development tools.
