(Instead of blindly down-voting ...) would you please point out my error? Seeing a negative number tells me nothing, although I am quite used to it by now. Obviously, the my variable must be declared somewhere, and in addition, it must be set to empty-list or undef (if this is running in a persistent environment such as mod_perl). It is genuinely my understanding that declaring the variable within one (in-lined) sub, but using it in another, is Not A Good Thing.™ Please explain the error of my ways.
Edit: Was the source-code revised since the first time I saw it, or is it just that my glasses are dirty? I don’t think I saw multiple my declarations for the array. More cof-fee... more cof-fee...
It occurs to me also in re-reading that the my declaration is also the only place where the variable in question is set to empty-list. Therefore, if the code repeatedly followed another path, the array would continue to grow. (Although I’d expect that you would be able to see that happening very easily.)
I also don’t see anything in the fragment that was posted that would account for a runaway memory leak.
I really want to know, as any Monk would do, where I went wrong on this comment! Thanks in advance.
