Date: Sun, 2 May 2004 10:12:28 +0100 [thread overview]
Message-ID: <200405021012.28011.jdh30@cam.ac.uk> (raw)
Could Set (and others) be implemented polymorphically by using a comparison
function passed as an argument?
If so, what would be the implications of this approach? I think: you couldn't
use the type checker to enforce consistent comparison functions between two
different sets which were, say, being merged. I think you can enforce this
using the functor approach provided the Sets came from the same functor
"instantiation".
Functors appear to be somewhat similar to templates in C++. Does the functor
approach produce more efficient code as it is partially specialised over the
comparison function?
Also, can functors map to functors as well as modules? If so, code could be
progressively specialised...
Cheers,
Jon.
