This problem happens because the std.experimental.allocator.common file

The short term solution is to open the package.d file in you dub 
packages ... folder and fully qualify every usage of the Ternary 
identifier with std.experimental.allocator.common.Ternary instead of 
"Ternary" with find & replace.

Both Ternary definition seem identical to me but you can not fully 
qualify them with std.typecons.Ternary because the last two usages 
require the definition in the common.d file for some reason I got two 
new errors when I tried that.

The long term solution would be for either Andrei or Brian to rename 
their Ternary stucts, as Andrei points out it does of other names such 
as Trinary. I suppose also that Brian could decide which Ternary 
definition he wants to use, instead of importing both although he may 
need other things is both imports besides Ternary.
