I don't know of a built-in pragma but you could look into Params::Validate: http://search.cpan.org/dist/Params-Validate/ "The Params::Validate module allows you to validate method or function call parameters to an arbitrary level of specificity. At the simplest level, it is capable of validating the required parameters were given and that no unspecified additional parameters were passed in. It is also capable of determining that a parameter is of a specific type, that it is an object of a certain class hierarchy, that it possesses certain methods, or applying validation callbacks to arguments." It's not automatic though -- you've gotta maintain a proper call to the validate() subs in your sub. -t _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
