Are there cases FP> where this would be useful, and not confusing as here ? why would it warn? a simple system could just put some subs into a separate file as a module and load them into main:: for use by the main script. no need for exporter as everything is in the main:: name space. remember, the package has nothing to do with the file name. all package does is set the default namespace for code that follows. the convention is to keep the package name and file name related so importing can be done. but in OO modules no importing should be done so again there is no need to keep the package and file name related. uri -- Uri Guttman ------ [email protected] -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] http://learn.perl.org/
