struct T
{
~this() @system {}
}
static assert(!__traits(compiles, (T) @safe {}));
static assert(!is(typeof((T) @safe {})));
CODE
----
This is an idiom that emerged from working on dup [¹] to quickly check whether
a struct has a @safe dtor or postblit.
The postblit check `__traits(compiles, (T b) { T a = b;})` works fine.
