Exploring Programming Language Architecture in Perl

Exploring Programming Language Architecture in Perl is an online book using the Perl programming language to explore various aspects of programming language architecture.

Book Description

This book presents an informal and friendly introduction to some of the core ideas in modern computer science, using the programming language Perl as its vehicle.
The book takes the form of a series of working interpreters for the language PScheme, which is a variant of Scheme. Each version of the interpreter builds upon the previous one, until by the end of the book the PScheme language is quite fully functional and has some interesting surprises.
