And I think that there are older bug reports which are similar. Regardless, 
attribute inference is pretty poor right now. A _lot_ of Phobos doesn't have 
its attributes being properly inferred precisely because the compiler stops at 
the first level of templated stuff rather than fully inferring a template, which 
quickly makes attribute inference nearly useless. It should definitely be fixed 
at the compiler level though. Anything else would just be patching holes in a 
sinking ship.
