Crystal is comparable to Java in performance. I am impressed with it. See https://github.com/nukata/little-scheme#performance https://github.com/nukata/little-s

  I have just updated my Scheme interpreter in Crystal (https://github.com/nukata/little-scheme-in-crystal https://github.com/nukata/little-scheme-in-crystal), which I used on the above benchmark test, along to Crystal 0.34. The release notes of Crystal 0.34 say "Having as much as possible portable code is part of the goal of the std-lib. One of the areas that were in need of polishing was how Errno and WinError were handled. The Errno and WinError exceptions are now gone, and were replaced by a new hierarchy of exceptions." So I have modified rescue ex: Errno raise ErrorException.new(ex.message, NONE) if ex.errno == Errno::EPIPE to rescue ex: IO::Error raise ErrorException.new(ex.message, NONE) if ex.os_error == Errno::EPIPE though it is still dependent on POSIX. >_<
