We need a good code font for the function signatures on dlang.org

[Andrei Alexandrescu via Digitalmars-d]

I was looking at 
https://github.com/D-Programming-Language/dlang.org/pull/1169 and that 
bold sans serif proportional text for the code is just... well let's say 
it's time to replace it.

What would be a good code font to use for those?


Thanks,

Andrei
