Well, actually, neither; I'm just sighing. Canadians of British descent
are too reserved to either laugh or cry in public.


But, seriously: (presuming David's referring to IDL and suchlike), perhaps
the main reason existing systems don't have such facilities is that I/we
didn't make it a priority to get a portable IDL subset out early, say back
in '83 while I was waiting for my committee to read my thesis. I'm not
sure why IDL derivatives aren't becoming more widespread now, though;
Scorpion (Rick Snodgrass' system) is in the public domain, and John
Nestor's Professional IDL and IDB (IDL-based persistent object store) are
commercial products.


I think there's a few articles on IDL in the comp.compilers archives.
