http://d.puremagic.com/issues/show_bug.cgi?id=5368 Summary: Remove Typesafe Variadic Functions for class objects Product: D Version: D2 Platform: All OS/Version: All Status: NEW Keywords: spec Severity: enhancement Priority: P2 Component: DMD AssignedTo: nobody@puremagic.com ReportedBy: bearophile_hugs@eml.cc --- Comment #0 from bearophile_hugs@eml.cc 2010-12-24 00:47:44 PST --- I suggest to remove a feature from the D2 language, "Typesafe Variadic Functions" for class objects: http://www.digitalmars.com/d/2.0/function.html This is the example in the docs: class Foo { int x; char[] s; this(int x, char[] s) { this.x = x; this.s = s; } } void test(int x, Foo f ...); ... Foo g = new Foo(3, "abc"); test(1, g); // ok, since g is an instance of Foo test(1, 4, "def"); // ok test(1, 5); // error, no matching constructor for Foo In the last years I have never used this feature, so I think it's not useful often enough. Once the feature is missing you have to replace code like this: test(1, 4, "def"); With: test(1, new Foo(4, "def")); So it doesn't seem a significant loss. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

What was the rationale for adding this? Is it some feature ported from another language? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
