Dear Monks,

I got a module which handles caching of various items. Items may be changed far away from the module actually filling the cache and I want to provide a way for scripts to force cache refreshing even if the source actually getting/setting the data is another file.

My idea was a global

our $FORCE_REFRESH = 0;

in my Cache module which should be set to 1 to force all subsequent read's to fail and refresh the cache this way:

{
   local $My::Cache::FORCE_REFRESH=1;
   &some_sub_requesting_the_data;
}

I want My::Cache to complain (and refuse to force refreshing) if someone starts modifying the variable without using local.

I don't want a My::Cache::set_force_refresh() function because I'm pretty sure people will set it without resetting it as soon as possible.

Is there any way to detect if a variable is currently localized?

Thanks,
Sebastian
