[parenscript-devel] question about dolist

hi, I found that the following compiles to an error, I wonder if this is a bug or there is something I misunderstand. (ps (setf v (let ((x 0)) (dolist (i '(1 2 3)) (incf x i)) x))) where the error is:

The Parenscript form (for (i (#1=_js_arrvar467 '(1 2 3)) (#2=_js_idx466 0)) ((not (>= #2# #))) ((setf #2# #)) (setq i (aref #1# #2#)) (incf x i)) cannot be compiled into an expression. [Condition of type compile-expression-error]

Hope you help me, thank you.
