Summary: null Rebindable testing not supported Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Keywords: rejects-valid Severity: normal Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2010-11-21 18:55:50 PST --- This D2 program shows that you can't test if a class reference wrapped with Rebindable is null: import std.typecons; const class Foo {} void main() { auto a = Rebindable!Foo(new Foo); a = new Foo; assert(a !is null); // err } DMD 2.050 generates: test.d(6): Error: incompatible types for ((a) !is (null)): 'Rebindable!(const(Foo))' and 'void*' Is this the currently correct way to do it? (It works): assert(a.get() !is null); // OK I have seen the get() method is not documented on the site, so is that a temporary limitation caused by the unfinished "alis this" implementation? (Issue tagged with "Component: DMD" because I think it's a limit of "alias this"). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
