Date: Subject: Kevin Greer posted this to LtU recently and I though it was worth repeating due to the recent interest in dynamic features: <p> <pre> Constant := Object clone do ( with := method(msg, self msg := msg self activate := method(call message setName(msg asString); msg) ) ) // Lets try it out: Make PI a regular number PI := 3.1415926 // Make b a method that uses it b := method(PI+PI) writeln(b) // -> 6.283185 // Inspect bs "source" code writeln(getSlot("b") code) // -> block(PI +(PI)) // Make PI a constant PI := Constant with(3.1415926) writeln(b) // -> 6.283185 writeln(getSlot("b") code) // -> block(3.141593 +(3.141593)) // Still works but when we look at the code of b we see that // the PIs have been replaced with PIs value!!! </pre> Password:
