Hi all,
Does anyone know whether I can run ClojureCLR on .net compact?
Specifically I would need to run it on Windows CE. Currently the
application is written in C# which works ok, but I need to rewrite it
and I'm deciding between C#, F# and ClojureCLR.
Thanks,
David

Statically typed in what way? Java's type system doesn't seem
particularly suited to a functional programming language like Clojure.

because this would be interpreted as a function/var that was expected to be

Yeah, you should be able to avoid having a .crossover or .generic or
whatever in your namespaces; those are just examples based on my personal
way of organizing things.
You can put the crossover files wherever you want, as long as they're in
the classpath (even in a JAR). They don't need to be
