That's exactly right. Sorry if I was being over-terse in my original.
Fergus is of course correct that you can write any type application
as a partial type spec too, if the syntax is thusly extended. However,
I think the type-ap style would in many cases still be somewhat more
concise, so it's not clear to me that the two are redundant -- or that
if they are, which is superior...
Cheers,
Alex.
