std.emplace will continue to work as a way to build an object at a
specified address. I suspect that allocating and manipulating objects on
the GC heap in particular may have certain restrictions. One possibility
to avoid such restrictions is to have a function typify(T)(void* p)
which ascribes type T to heap location p.
That sounds similar to my gc_emplace function. The problematic part is
how to save that information in the GC.

Couldn't you store a pointer to the typeinfo within the
allocated memory? IOW, the first part of the allocated memory
would be the typeinfo* followed by the actual memory used to store the
value of the allocated T object.
