He means the compiled code of a lambda can't be GC'ed. He was creating new functions inside of an eval. The individual closures created as code executes are GC'ed like everything else. Since eval is rather specialized, and everyone recommends it be avoided in "normal" code, this is not a major problem. Plus, it is fixed.
