http://d.puremagic.com/issues/show_bug.cgi?id=3365 Summary: Safe casts: type modifiers Product: D Version: future Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: dfj1esp02 sneakemail.com 07:11:53 PDT --- C++ has const_cast to add or remove const modifier from type. Currently in D casting to/from const is unsafe as it doesn't protect from type conversions. Safe variants of const casts can be added with the following syntax: cast(const)obj; //to const-qualified cast(~const)obj; //to mutable cast(immutable)obj; //instead of assumeUnique cast(~immutable)obj; cast(shared)obj; cast(~shared)obj; I'm not sure whether cast(~const) should behave exactly as cast(~immutable). P.S. This doesn't impose any additional requirement on the runtime library. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
