I didn't interpret OC as calling Julia lispy, as much as saying that Julia is matched to SBCL's interactive machine code generation and inspection. I don't have a dog in that particular fight; I've barely touched either language.
Except, macros. I have never seen macro wizardry come anywhere near SBCL without homoiconicity.
edit: pre-coffee reading comprehension, apparently. The word lispy is _right there_ in OC.
