The synopses are contradictary over the way 'constant' works. First it says
that it is a declarator like 'my'. Then in S12 it shows
my constant ...
our constant ...
that is, independant from the my or our declarator.
Assuming the second way is newer/better, what is the grammar for this? Is it a
declarator if used on its own, or a different category?
Oh, and should it still say that if you leave off the optional 'my' or 'our'
that it defaults to 'my', or should it be 'our' like everything else?
