About proxySwap

[Dmitri via Digitalmars-d]

This was this one time when I was storing vibe's Bson objects in 
the array that I tried to use one of the mutation algorithms on 
it: bringToFront, and it did not work. At the time I had no idea 
of proxySwap but the Bson type apparently had one implemented 
according to the swap specialization used.

After a bit of head scratching, I figured the opDispatch is 
making the type look like it has anything implemented, so the 
question is:
How do I use mutation on sequences of (probably library) types 
with opDispatch but no proxySwap? Is wrapping the only 
alternative?
