Static Analysis too Aggressive

See attached code fragment with static analysis Notes from within RubyMine

The method has one argument - files_z, which the static analyzer claims can be uninitialized.

Also, the local variable priort is clearly initialized, but is apparently tainted enough by association with files_z through fz, that the static analyzer claims it can be uninitialized.

The static analyzer is a very useful feature of RubyMine, but too many messages can reduce its usefulness.
