Computer language are neither inherently interpreted nor compiled. This is an aspect of an implementation. There's also a bit of fuzziness in what compilation vs. interpretation means. At one end of the spectrum is an implementation which compiles source code into the native machine instructions for the target platform, at the other end is one which re-parses source code every time and interprets it. There are very few implementations at the second end of the spectrum, most 'interpreters' actually 'compile' source code into some intermediate representation for execution/evaluation. The MRI implementation of Ruby pre-1.9 'compiles' ruby source into an abstract syntax tree. Ruby 1.9 compiles to what are effectively instructions for an 'artificial' virtual machine, this is similar to how most Java implementations work, with detail differences. Similar 'byte' coded VMs have been used for implementations of languages such as C/C++ which are normally compiled to machine code. And there are cases where such implementations can outperform 'traditional' implementations on some platforms, because the executable code is more compact, keeping the working set size down and reducing virtual memory swapping/paging overhead. Lisp one of a triumvirate of the earliest programming languages (along with FORTRAN and COBOL) has a traditional implementation similar to Ruby 1.8, aided by the fact that Lisp is a homoiconic language which makes the 'compile' part particularly early. However, Lisp too can be compiled, the Scheme dialect, developed by Guy Steele and Gerald Sussman at the M.I.T. AI lab in the mid 1970s-early 1980s provided a hotbed for such activities. Sussman and Steele's original 'Lambda Papers' are seminal works which have informed quite a few language designers. http://library.readscheme.org/page1.html -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Github: http://github.com/rubyredrick Twitter: @RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale
