range properties that work in foreach

On the D2 online pages (http://www.digitalmars.com/d/2.0/statement.html#ForeachStatement)there is Foreach over Structs and Classes with Ranges My question is , is there a working example of foreach ( e ; range )? Iteration over struct and class objects can be done with ranges, which

interface problem

I got 2 classes which both (indirectly) inherit from a common base class and implement a certain interface I. Now I need to pass that interface to a function and need to call a function inherited from the base class inside. Naturally that function is not present in the interface and thus can't

Re: interface problem

Trass3r: I got 2 classes which both (indirectly) inherit from a common base class and implement a certain interface I. When possible show an example. You can fill/fix the following code to create an example of your problem: interface IFoo { void foo(); } class Base { void foo() {} }

Re: Static attributes aren' immutable

div0: Yeah, I *never* access static vars through an instance, I always use the class name. Somebody want to post in the main group? It seems there are few people that agree with you, but Walter has not answered about this yet, so you can ask him his opinion. I like to use a tidy language.

Re: range properties that work in foreach

Good range documentation comes from: http://digitalmars.com/d/2.0/phobos/std_range.html foreach only requires an Input Range.

Re: interface problem

Cast the instance to the base class and call the method? Surprisingly this does compile. What are the rules for casting between classes?

void initialization vs alignment holes

This is probably going a bit above my head, but the existence of alignment holes in the objects is accounted for, usually by setting them all to 0 upon initialization I suspect this isn't the case for void initialization; if my struct has some alignment hole I better not void initialize it if

Re: void initialization vs alignment holes

Re: void initialization vs alignment holes

Hello Strtr, Would you ever have an alignment hole if all the struct contains are basic types(excluding bool)? real, char[n], byte[n] and short[m] (for n%4 != 0 and m%2 != 0) might be an issue. -- ... IXOYE

Re: void initialization vs alignment holes

Hello Strtr, Suppose I'd still would like to use void optimizations, how do you clear the holes manually? IIRC zero filling a block is likely cheaper that zero filling holes in it. I'd avoid =void unless you know you will be copying structs into the space (that will copy the holes as
