We've been able to treat ns declarations *as* declarations for the
most part, which is nice. IMO, last-var-wins pulls the veil away even
more on the fact that namespaces are probably the most pervasively-
stateful part of clojure.
I remember various proposals floating around a long time ago to

Assuming your environment is set up properly w.r.t. classpaths, spring
should work just fine in a REPL. We use spring security for our
compojure webapp, and the spring context starts up as expected in our
enclojure REPLs. FWIW, we do use maven and the clojure-maven-plugin,
which informs
As Clojure moves towards being self-hosted, fewer and fewer of the
data structures will be implemented in Java, thereby ensuring
dependence on the Clojure runtime. Just FYI.

Compilation is driven by namespace load-order, so just ensure that you
add a (:require com.foo.IFoo) to the ns declaration where you define
the Foo class.
I seem to remember suggesting that Clojure should implicitly attempt
to require namespaces corresponding to classnames being
If you're not using a parallel garbage collector (which is the case by
default), then generating significant garbage will result in not-
insignificant GC pauses. Allocation itself isn't a synchronous
operation, but the default GC is.
Most java profilers have thread-related tools that allow

No, compilation should not be included. You mention make; it is a

Is that the right way to do it?
