Hi Paul, Don't hold your breath. Whenever we engage in our little daydream called "What would we do if we could start again", which as far as language is...
I'd use (A B)<-C D myself, and a verb B would cause an error. Such dreams are good: in one case I built an object setter: 'objectname.property' is value and...
John, Randy, Yes, that is what I thought should happen. Morten, all, I agree completely with your sentiments regarding modified assignment (and certainly was...

I've been struggling with a problem: I have an object and I am multithreading. Certain threads may update properties in the object. Other concurrent threads...

Hmmm, that could cause a problem -- any use of .Net's Monitor mechanism ("Lock" keyword in C#) could deadlock if that's the case. (Suppose Dyalog threads A...
