Phel has deep PHP interop built into the language: call any PHP function, instantiate classes, access globals via the php/ namespace from anywhere in your code.
We also ship a Phel nREPL: a bencode-over-TCP server (phel nrepl) compatible with editor tooling like Calva, CIDER, and Conjure. Connect your editor and evaluate Phel code against a running process directly.
Phel compiles a Clojure-flavoured Lisp to PHP. v0.36.0 ships exact rationals (1/2 literals), arbitrary-precision BigInteger with overflow auto-promotion, BigDecimal, first-class Vars (#'sym, alter-var-root, with-redefs, watches), and new value types (UUID, Queue, MapEntry). Plus REPL and test boot are notably faster.
Let’s assume you already know what the agile manifesto is. Let’s consider that you apply most of the “extreme programming” values, principles, and practices. How can you work with other teams that aren’t agile?
