CGI to mod_perl Porting. mod_perl Coding guidelines

If the variable contains a reference it may hold onto lots of unecessary memory (or worse) if the reference is left to hang about until the next call to the same handler. For such variables you should use local so that the value is removed when the handler subroutine exits.

  my $query = CGI->new;

becomes:

  local our $query = CGI->new;

Hi, when I change the
our $query = CGI->new;
to
local our $query = CGI->new;

The $query var becomes undefined. the $query is a global variable in a module.

I wonder why ?
