While trying to track down a type error in a Pugs program today, I thought of what could be a handy debugging feature.
I would like Perl 6 values to capture the call stack when they're created and store them into a property called "confess" (Autrijus's name). $value.confess would then return an array of Caller objects, which could be inspected to determine where a value came from. It might even be wise to have it capture the call stack each time the value is mutated. Since this would likely be expensive, I suspect it should be optional and turned off by default; however, this would probably be a global setting, not a lexical one. -- Brent 'Dax' Royal-Gordon <[EMAIL PROTECTED]> Perl and Parrot hacker
