I'm willing to add this for 5.16 if we can come to agreement on the syntax. One possible scenario is that we use legal, but essentially nonsensical syntax to specify these operations. One example is to possibly use [...&&...] to mean intersection, as some language does; I can't recall who. Having '&&' in a bracketed character class is legal, but it's effect is no different from the more clearly expressed single '&'. This could be handled, if that's what the consensus comes down to, by deprecating a doubled & in character classes in 5.14, so that 5.16 could take that over. I'm not necessarily advocating that, but if it is the decision for some of the new operations, we need to know it in time to add it to 5.14. Other possibilities include, as mentioned on this forum before, using a currently illegal syntax, or expanding 'use re' to allow the user to specify they want new syntax. But the bottom line is that if we go the deprecation route, it should be considered soon.Thread Next
