Hi all,
I'm trying to understand functors (so I can teach them and use them),
and I spent a lot of time trying to figure out why a functor statement
doesn't do what it seems like (to me) it should do. Probably I'm
trying to do something that is wrong, so I'd appreciate an
explanation.
What I did was to put te following code in FunStmt.oz:
declare
functor FunStmt
System(showInfo)
define
X = 1
in
{System.showInfo X}
end
And then I tried several things, all of which seem to have no effect.
I did:
ozc FunStmt.oz
ozc -e FunStmt.oz
and after both of these, there are no error messages of any sort, but
there is no file FunStmt.ozf produced. Similarly feeding the buffer
to the OPI doesn't given any errors, but nothing happens in the
emulator either.
Can someone please explain it?
