Is this how @disable is supposed to work (D2 code)?
Is overriding a disabled function meaningful?
import std.c.stdio: puts;
class A {
void foo() { puts(A.foo()); }
}
class B : A {
//@disable override void foo(); // Linker error
@disable override void foo() { puts(B.foo()); }; // OK

Hello.
Say I have a [struct] template T, which takes a param S.
Any T!(S) satisfies a certain template constraint W, so I can use any
T!(S) the same way. I want to be able to store heterogeneous T!(S) in a
single list. Is there any good way to express the type for this?

What I had in mind was:
struct S
{
int foo(int x) { return x * 2; }
}
struct S2
{
int foo(int x) { return x + 2; }
}
void main()
{
S s1;
S2 s2;
IW[] ws;
ws ~= makeW(s1);
ws ~= makeW(s2);
assert(ws[0].foo(3) == 6);

Yes, all items in an array must have the same size. If you want items of
different size you have to add a level of indirection, storing inside the array

I don't know, things like parsing support for compile time strings,

My project seems to be growing ctfe, and it's all horribly hacky and
