Hey, just wanted to know whether something like this would be possible sowmehow: struct S { int m; int n; this(this) { m = void; n = n; } } So not the whole struct is moved everytime f.e. a function is called, but only n has to be "filled"

Destructing Struct

Hi :), What i thought was that when i create a struct dynamically i can just deconstruct it with __dtor lets say: struct U {...} struct S {... private U _member;} S* p; p = cast(S*)malloc(S.sizeof); // just run that if it compiles, for simplicity // we dont use __traits(compiles, ...)
