Wouldn't in all perl require a way of overloading 'punctuational' operators that don't exist? (Well not exactly overloading as there's nothing originally.) One application would be a "Wire" class I am working on which handles 4-state values: if ($foo === $bar) if ($foo !== $bar) The majority of Hardware types, the target audience, would recognise this immediately as a operator from the Verilog Language. The mess it would make in the tokenizer would be a real problem. Yuck. [BTW, Verilog has 4 state values one state of which is unknown -- basically undef. It also has operators that have special function on unknown, like === which works different from == only in its behavior with unknown.] -WilsonThread Previous | Thread Next
