Is this a generally agreed-principle that the PHP community believes is important? If so, shouldn't we quantify what the cost is and who would bear that cost, and then compare it with a quantified cost to be born by the people whose working scripts would break? Also if so, should we then not also consider other peculiarities that cause people to take time understanding/dealing with? A really good example would be the difference in needle and haystack order for parameters passed to array-related functions. Certainly far more time is spent dealing with those peculiarities than time is lost related to the backtick operator? So if we as a community agree that time spent understanding peculiarities is a solid justification for an RFC to be accepted, then it seems to me the PHP can support a large number of RFCs given all of its different peculiarities, no? -Mike P.S. I can go either way given the above on both topics. But having an agreed-upon principle — or not — would really streamline debate.
