This blocks to user File as Stream for msgpack-d.

This doesn't seem necessary :)

 static 
 assert(isOutputRange!(typeof(stdout.lockingBinaryWriter), 
 byte));

static 
assert(isOutputRange!(typeof(stdout.lockingBinaryWriter()), 
byte));

typeof(stdout.lockingBinaryWriter) is a function type. You need 
the ().

Ooops! Thanks! :-)

Not sure what you mean by this, because 1) it's not even doing 
anything if there are no dependencies on Dub packages, and 2) 
test cases should be self-contained and not have external 
dependencies anyway. If the test case can only be reproduced with 
some compiler switches, a shebang using rdmd (with --shebang for 
multiple switches) can be used to illustrate it.

Looks like isOutputRange is not checks "put" method properly?
