Type inference in array literals

I was really surprised by the fact that the following code does not work (DMD 2.048 infers the type of the array literal to B[], not Object[]): --- class A {} class B {} void main() { Object[] foo = [ new A, new B ]; } --- Is this by design? If so, what are the reasons for not using the

Re: Type inference in array literals

D uses the last element in the array literal to select the type. I think there was a discussion on why a common type wasn't used, but don't remember the conclusion. It would be nice if it used the item you are assigning to and check they can convert to it. klickverbot Wrote: I was really

Re: Type inference in array literals

Jesse Phillips: D uses the last element in the array literal to select the type. That's not true, this doesn't assert: import std.stdio: writeln; void main() { auto a = [1, 1.5, 2]; assert(is(typeof(a) == double[])); } I think it uses ?: on all elements, to infer the type. Bye,
