Are anonymous enums mostly available for performance reasons?

I use them to create D bindings to C libraries. They are useful for 
translating both C enums and #defines. Plus, if porting C++ code they 
make a good tool for translating global constants. Also, and this is a 
big one for me, anonymous enums generate no TypeInfo, which can save a 
lot of space in the binary over named enums.
