https://d.puremagic.com/issues/show_bug.cgi?id=11481 Summary: Clearly note all explicit casts are forwarded to `alias this` if there is no `opCast` Product: D Version: D2 Platform: All OS/Version: All Status: NEW Keywords: spec Severity: major Priority: P2 Component: websites AssignedTo: nobody puremagic.com ReportedBy: verylonglogin.reg gmail.com 16:39:36 MSK --- People tend to think explicit cast behaves as no-op if there is an implicit one. Documentation must clearly note it's wrong and `opCast` is tried to be called. Also a list of operations rewritten as explicit cast like `if(someStruct)` must be provided as people tend to forget invisible explicit casts exist. Appendix: * Filed invalid bugs because of this: Issue 3537, Issue 6777, Issue 7985, Issue 9151. * Lockup mechanics explanation by Kenji Hara: Comment 2 of Issue 11161. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Appendix: * Filed invalid bugs because of this: Issue 3537, Issue 6777, Issue 7985, Issue 9151.Issue 9151 is the only instance of this. Simply adding an alias this must not result in hijacking, so the current behaviour is unacceptable for the other issues.* Lockup mechanics explanation by Kenji Hara: Comment 2 of Issue 11161.How exactly DMD derives unreasonable behaviour is not relevant for answering the question whether the behaviour is reasonable. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
