About with-meta source, can explain it by itself?
Hi,
I read the source about with-meta, and find def with-meta using
with-meta, can it? someone give a explain?
user= (source with-meta)

map m as its metadata.

Re: [ANN] avl.clj: sorted maps and sets with fast rank queries via nth
As of 0.0.3, avl.clj offers sorted maps with lookups unambiguously faster than those of the built-ins. Construction times for large instances are also faster thanks to transients. The lookup performance comes at a cost in the form of slower non-transient assoc/dissoc. I've posted some benchmark results to clojure-dev; I'll post a similar message here once I'm ready to cut an 0.1.0 release (which basically needs more tests for added confidence, a test suite on the ClojureScript side and such).

Re: About with-meta source, can explain it by itself?
Actually with-meta's definition does not refer to with-meta. Rather,
it calls withMeta, a method in the clojure.lang.IObj interface which
the first argument to with-meta is supposed to implement.

Re: About with-meta source, can explain it by itself?
You are right, i noticed it calls withMeta, but in the expression,
actually use with-meta to define with-meta, it's very strange, thank you
very much!

Re: About with-meta source, can explain it by itself?
The with-meta in (fn ^:static with-meta ...) is just the name the
function created by the fn form will know itself by. It will also be
used as the final segment of the name of the class of this function
object. It's not being evaluated in this position, and in fact it
could be replaced with, say, foo (and then you'd get mentions of a
class with name ending with foo in stack traces caused by improper
uses of with-meta). On the other hand, the fact that the function has
a name means that it could call itself through this name, return
itself as a value etc.; effectively giving a function a name creates a
local holding the function itself within the function body.
Cheers,
Michał

Re: two pass compilation, intern and def
Well, do actually means execute all of the following forms, sequentially, at this point. It seems to me that the position of saying this also works when this point is the top-level is sensible. I do not know what your actual use-case is, but, as Meikel said, it seems a bit strange to use intern if you know the symbol at compile time.

Because intern happens at runtime. It's a normal function. The above intern call is easily translated to the def. intern is only interesting when bob3 is computed based on runtime information, which is not available at compile time. But then the compile cannot special case it anyway. From a user perspective, I think that this is very messy. I can see your example about do, but then I think using a common form like do is a mistake; having do behave differently depending on whether it is top level or not is exposing a lot of detail that should not be.
