My update was poorly worded (fixed). The supported conclusion is that your blocks are not structured like you expect. Try it with the posted code.

I find it surprising that you are using strict, given that there are no my statements in your snippet. It is a bad idea to use loop variables that are not limited to that loop in scope. This is particularly risky with C-style loops.
