In software engineering there aren't many free things. 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.
