Hi Jose,
I think that Common Lisp macros are, strictly speaking, more powerful

That's only true for syntax-rules macros. syntax-case macros, which
most schemes provide and are required by R6RS, are,

Maybe some day we can have alternate distributions with more full-featured

As David mentioned, *unchecked-math* is documented as a compile-time flag.
The coercion functions are a bit muddled by the changes to primitive math
in 1.3. In Clojure 1.2, you could get primitive int inside loop/recur by
calling `int` in the loop initialization. You can still do that in 1.3,

I'm migrating some code from 1.2 to 1.3, and one of the things I've
encountered is that it no longer accepts ^map as a type hint. It's
happy if I use ^clojure.lang.PersistentArrayMap, but that's quite a
mouthful.
Is there a more compact abbreviation I can use? Where are such things
documented?

I've added a little overview in the code, hopefully this should make things
clearer. Also I made parse, the main invocation point, extensible to users
of the library.

the best approach... but sometimes it just might be. For those rare

I noticed in my code that I often nest a let inside an if-let, or vice-

that binding expands into an if-let.
E.g.
