No, that's a common misconception. Closures and anonymous subs are two totally separate things, although they can be used together. See the explanation here: http://perl.apache.org/docs/general/perl_reference/perl_reference.html#Understanding_Closures____the_Easy_Way There is more discussion in the list archives. > My version uses a regular (named-) sub and the scope of the variable $r > should be lexically local to the enclosing block. And it is, but your sub creates a closure so that when $r changes in the enclosing block that is not seen in your sub. The simplest solution is to pass $r every time. > Moreover I've read that Apache->request should be avoided in mod_perl2: > http://perl.apache.org/docs/2.0/user/porting/compat.html#C_Apache_E_gt_request_ That only applies to threaded MPMs, and modules you release that others might want to run under threaded MPMs. - Perrin -- Reporting bugs: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html
