The Parrot virtual machine hit 1.0 in March of this year, with a second production release (1.4) this week. A virtual machine like no other, Parrot targets dynamic languages such as Perl, Ruby, Python and PHP. It incorporates an object-oriented assembly language, is register-based rather than stack-based, and employs continuations as the core means of flow control. It hosts a powerful suite of compiler tools tailored to dynamic languages and a next generation regular expression engine. This talk explains the overall architecture of Parrot and the theory behind that architecture.
