At last! An answer to a long-standing annoyance I found with the language...
how to put the full type declarations (implementations) into the package
body, where they belong!
I had thought it was meant to be possible, but had never seen exactly how.
(presumably this one way to get physical isolation between different
components in a large system, so changes to data types don't trigger
recompilation of everything)
time to tidy up some old code of mine...
Thanks for pointing this out, guys!
