It seems to me that it would be more useful, if you offered two options
do idx over dir firstcount i
say "entry #" i": idx="idx "dir[idx]="dir
end
and
do idx over dir finalcount i
say "entry #" i": idx="idx "dir[idx]="dir
end
where 'firstcount' is incremented as if the first statement in the loop
was i=i+1, and 'finalcount' happened as if it was the final statement.
Then an 'iterate' within the loop would have no effect on a firstcount
counter, but would prevent incrementing of a finalcount one.
Maybe you could even have
do idx over dir firstcount i finalcount j
say...
end
which would be equivalent to
i=0;j=0
do idx over dir
i=i+1
say...
j=j+1
end
