While this provides an elegant solution for growing the language, the performance penalty incurred by call-by-name parameters, boxing and anonymous functions is high. We show that inlining alone is not enough to remove this overhead, and present a solution based on decompilation of library code combined with inlining, dead code elimination, and copy propagation. We evaluate our approach on two language extensions, Java-like assert and C-like for-loops and show improvements of up to 45%.<br /> <br /> http://wiki.jvmlangsummit.com/pdf/15_Dragos_scala.pdf<br /> <br /> === Author Bio ===<br /> [[Image:iuli.jpg|60px|thumb|left]]<br /> [http://lamp.epfl.ch/~dragos Iulian Dragos] is working on the [http://scala-lang.org Scala] compiler since 2004, being responsible of the JVM backend and compiler optimizations.
