For some of the Scala features you have to pay with a higher amount of memory used by the Java virtual machine, and with the compilation time of the function optimizations (and type system management) done by the Scala compiler. There is a faster Scala compiler, named fsc, but I don't know how fast it is for larger projects.

Ok, I see now that my answer can be misinterpreted. When I wrote the 
answer I was actually referring to the lambda syntax used in the "map" 
function. This is just syntax sugar that D could use as well with no 
overhead.
