re: [type declarations for the USING variable in hash-table syntax]
It looks like whichever variable gets relegated to the USING clause
can't be given a type specifier. Have I missed something?
Sigh, no Neil, it looks like "we" missed something.
What would you think of having an optional type-spec for the USING
variables in the FOR/AS syntaxes 6 and 7? [see X3J13/89-004, p2-13].
The bnf for USING parts would then look like:
[USING ({HASH-KEY | HASH-VALUE} <other-var> [type-spec])]
This would, of course, also apply to the package iterators.
