This is a nice bug report, and to solve this kind of code the D compiler
probably needs a little more powerful type inference. If you are able to do
this improvement with a reasonable amount of work and code, then it's OK.
Otherwise an option it to mark this with WONTFIX to keep the D compiler
simpler. A better type inferencer may require more compilation time and a
bigger compiler.
