I was fixated to a) not forgetting a side note that could be annotated, as I did in one of my last posts b) the initialisation part =(), having a situation in mind I just had before in a mod_perl context, where, in template code, a variable got not reset due to a missing =(). But it was... an our variable. And against the "my variable closure phenomenon" the =() is also useless. So again thanks for a hint and of course my above statement is wrong. > Do you really understand what my() does? yes I think so.
