So how 'bout we have two methods, such as: LW> $foo.variable_is LW> $foo.value_is hmm, in catching up with mail i saw damian's long property exegesis and i replied with a suggestion asking to split the value/permanent (or as above value/variable) props and then i see this. good to know i am on the right wavelength. but can a code ref a set of variable properties? that is why i am using the term permanent (or set at compile time and unmutable). another point: how can you delete properties? obviously this can only be done with value properties. an accessor method has no clean way of separating plain access $foo.bar() from some way to assign a null list to it. you can assign an explict undef but that is not the same as deletion. so a delete_value_prop func/method should be supported in some fashion. uri -- Uri Guttman --------- uri@sysarch.com ---------- http://www.sysarch.com SYStems ARCHitecture and Stem Development ------ http://www.stemsystems.com Learn Advanced Object Oriented Perl from Damian Conway - Boston, July 10-11 Class and Registration info: http://www.sysarch.com/perl/OOP_class.htmlThread Previous | Thread Next
