Let us clarify the goal of these enhancements? i assumed that the goal of these enhancements was to allow code like hello+:=$(world) create 'hello' as a simple variable, if 'hello' does not exist yet. After reading your != example, i realize i misunderstood the meaning of option one. Let me correct myself. If the only goal was to allow +:= create a simple variable, then can we do the following? "If no variable with this name exists, then +:= creates a simple variable, and +:::= creates an immediately-expanded-and-escaped variable. Otherwise, +:= and +:::= behave the same as +=". If we go with this, then there is no need for +!=, because +!= would behave as +=. Similarly, there is no need for +::=, because +::= would behave as +:=. regards, Dmitry
