I kinda agree under the assumption that a static variable is only used
in a particular context and there is a reasonable requirement to do so.

The above does not qualify as I pointed out in my other reply. Just
because it looks like strict local usage at the first glance does not
make an argument, really.

I'm amazed that it's so hard to see that this


pattern is broken to begin with.

So why are you arguing about the placement of this variable in the first
place instead of actually looking at the code, wondering about the
obscenity and then asking about the call ordering?

In case that I might miss something important here due to my lack of CS
education, please let me know.
