As you can see, there is a workaround: use ^double, not ^Double. This
You are right demanding a base case. I don't deny that any more. As stated
above, me as a beginner, experimenting for experience, took the well-known
Fibonacci corecursion (with base case) as guidance in setting my first
prime corecursion code with range, and then reduced the base case from '(2
The tuts. are awesome!

Also note that testing with the Rhino REPL is not informative about
performance in anyway - you absolutely need to test your code against the
modern JS engines - V8, JavaScriptCore, or SpiderMonkey (with JIT turned
on). For code like this they are often 100X faster if not far greater than
that.

Thanks for the feedback!
Defining the two helper functions outside of the function-scope doesn't seem to
have any effect on the performance numbers.
…but I have to confess that all testing was done at the repl without any
optimization so far…

I have discovered some odd behavior when type-hinting fns with
^System.Double:
user=> (defn bar [^System.Double d] d)
#'user/bar
user=> (bar 1.2)
2.35293190771409E-316
user=> (bar 1)
2.35069794048985E-316
The same behavior occurs when extending double via extend-protocol or
extend-type:
user=>
Oh though before you lift them out by hand - I would double check that
:simple optimizations doesn't already do this for you :)

closures inside the body of a function are not free in JS. I would lift
those helpers out. In general I see no benefit to writing your "fast" code
in JS - all the facilities for writing efficient code are available in
ClojureScript itself. I agree that it's not completely clear what subset of

proxy is basically a more interop-oriented version of reify though, and it
can extend classes, and you can use proxy-super to call superclass methods
from there.

reify can only implement interfaces and protocols, so there aren't any
superclass methods to call (except the ones in Object I guess).

Thanks,
is there something like that for reify?

CLOOJ is the best.
Simple, efficient, no installation, everything you need (of course you also
need lein).
If you want to have headaches trying everything around you'd better do it
after have learned the basics otherwise you may give up believe me.
