yes exactly! In the commit that github shows last line 238 is line 244
in my current branch...Since you're looking into it i can commit
everything now so we're all on the same page...

Hi everyone,
I came back to a project of mine after a couple of months only to
be surprised by some cryptic exception! Imagine a 2d vector:
(def coords [[0 0] [0 1] [1 0] [1 1]]) ;;vector of vectors of longs
;;but let's try ints which are cached:
(def coords
(mapv #(apply vector-of :int %) [[0 0] [0 1] [1 0] [1 1]]))
;;vector of vectors of ints
everything seems great right? well, now my namespaces don't even
compile! This is my representation of the 'board' in a game which
means that I'm only reading from this vector nothing else! I am
getting CompilerException java.lang.RuntimeException: Can't embed
object in code, maybe print-dup not defined:
clojure.core$reify__6184@1eb42164,
compiling:(Clondie24/games/chess.clj:244:1) where line 244 is just
a 'defn' with its argument vector...as soon as I comment out the
conversion to unboxed int primitives everything works again! doing
(pst) does not help at all! Look at this:
user=> (pst)

this is clearly not my code! everything is clojure.lang.Compiler
related!
what is happening exactly? can anyone explain? I'm not doing
anything 'weird' in the function reported in the exception just
reading the vector.
