I added univ and documented it.
Something seems to have gone wrong with the <param-type> defintion on page 212.
Having a better look, the <parameter-declaration> rule defines just one
parameter. So, we get instead
formal-parameter-list = "(" [ parameter-declaration { ";" parameter-declaration } ] [
"..." ] ")" .
parameter-list = formal-parameter-list .
comprising also the "ellipsis" parameter, which, according to Appendix D.6 of
the Programmer's Manual is functionally equal to the varargs
keyword.
Added to the diagrams.
I changed the diagram to be more clear (hopefully).
But the rule for <formal-parameter-list> on page 211 now suggests that "..." can be used in the
middle of the other declarations, which is not true.
formal-parameter-list = "(" [ parameter-declaration { ";" parameter-declaration } ] [
"..." ] ")" .
Can't a variable also be qualified ? Therefore ?
variable-reference = qualified-identifier .
Yes.
I didn't see a rule for <variable-reference> yet in the Language Reference.
But to parse that, the rules for <interface-part> and <declaration-part> need
something like an <operator-declaration-part>, don't they ?
Yes, I had come to this conclusion myself, and I added it.
I can't find the change yet.
