But maybe this answers your question?
import std.stdio;
struct S
{
int* p;
this(this)
{
++*p;
}
}
void main()
{
immutable i = 0;
auto s1 = immutable(S)(&i);
auto s2 = s1;
assert(*&i == 0);
}
Consider that when passing a variable you can always remove
top level const-ness because a copy is made. This holds for
returns, parameters, assignments, ...
Post-blit is no different. The issue as I see it, is that D
doesn't have strong support for this notion of head-mutable or
D has it for primitives, such as pointers, slices...
else it would work with this type during post-blit:
struct S
{
immutable(int)* p;
this(this)
{
++*p;
}
}
Unsure how that's relevant? This code looks wrong to me no matter
how you look at it?
