6		BTW, this approach not only leads to memory leaks, but also ~~gives the wrong -- or at least, unexpected by most programmers --~~ semantics for captured mutable variables. And since changing that would be an incompatible change, it's not likely that either the memory leaks or the semantics will be fixed.
