In issue 5409 I have asked for another feature that helps to avoid bugs. This feature request is backed by a large number of similar bugs found in already written production code. This not a proof, but for me it's enough evidence to forbid the (!x & y) pattern. I'd like something that justifies to add this feature to D, something beyond just "C# has it, kind of". I know that it's hard to find, but on the other hand you are asking something to programmers (it's optional, but it's not hard to see D shops with coding conventions that ask to always use the ref/out at the calling point), so the feature must give something back. This feature improves code readability, but in D you also have "const ref" that semantically-wise for the caller is not that different from a pass by value. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
