Type properties

Why is init allowed to be redefined but not sizeof?

dmd 2.069

import std.stdio;

struct Foo {
    static int init = 5;
    static int sizeof = 0;
}

void main()
{
    writeln(Foo.init);
    writeln(Foo.sizeof);
}

Error: variable integer.Foo.sizeof .sizeof property cannot be redefined
