Tamreen Khan presents Pharen, a Lisp to PHP compiler.

PHP has been criticized for being bad, among other things. Pharen is a Lisp to PHP compiler that tries to solve the syntactic side of this issue, taking code in the lispy dialect and spitting out the PHP equivalent of what you wanted to do. Tamreen Khan covers more on the rationale of the project, features that make it lispy (parentheses, tail recursion optimization, macros), features that make it work with PHP, and other stuff.

Tamreen Khan is a student studying computer science at NYU. He usually works with PHP or Python, sometimes professionally, and has occasionally made some even worse languages.
