First, it actually does compile, I think because the compiler
recognizes that LocalS is POD (plain old data), without methods, so it
doesn't need a context pointer.
e.g.:
auto make(T)() { return new T(); }
...
auto x = make!LocalS; // ok
If you add a method to LocalS, then make!LocalS fails to compile.
However, strangely, p!LocalS still returns true, I think that is an
error.
Thanks for your answer. Now I understand that POD matters here.
When I add a dtor: `struct LocalS { ~this() {} }`, the `p!LocalS` got
false.
There is still a bug though. if p!T returns true, but make!T doesn't
compile, then something is inconsistent.
