All functions returned by a given arity of partial or comp are of the same
Java class under the hood, whereas defining an anonymous function always
generates a new class, and I've heard that fewer classes can result in
better performance from a JIT perspective. But I'm just speculating and

It's been a long time since I looked at this, but as of a few years ago,
the biggest noticeable performance detriment of comp or partial was likely
to come if you pass enough args to hit a "& args" overload, which requires
creating a fresh object array at each call, when the underlying function

Is there a performance benefit (or detriment) to creating partial functions?
Other than the potential reduction of complexity, is there a difference between
using partial & comp and defining new functions?

Thank you, Marc!
I will try to use your example to develop more general "instance" function.

Hey Ru,
I'd also add that `new` is a special form, not a function. It is evaluated
at compile-time, which is why the macro doesn't work. You can also try
macro-expansion to see what's going on:
(defn itest [x] (macroexpand-1 '(instance x)))
=> #'user/itest
(itest java.lang.String)
=> (new x)
