feat(module): adds cyclic dependecy check

[Samy-33]

Cyclic dependency check

➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/a.jank
(ns a
  (:require [b]))
➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/b.jank
(ns b
  (:require [a]))


➜  compiler+runtime git:(optimize/module-system) ✗ ./build/jank --module-path  /home/saket/Documents/oss/jank/compiler+runtime/dev/src repl
Bottom of clojure.core
clojure.core=> (require 'a)
Exception: {:error :assertion-failure, :data {:msg Cyclic load dependency: [ /a ]->/b->[ /a ]}}
clojure.core=> ^D
➜  compiler+runtime git:(optimize/module-system) ✗ nvim dev/src/a.jank
➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/a.jank
(ns a)

(require 'b)
➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/b.jank
(ns b)

(require 'a)


➜  compiler+runtime git:(optimize/module-system) ✗ ./build/jank --module-path  /home/saket/Documents/oss/jank/compiler+runtime/dev/src repl
Bottom of clojure.core
clojure.core=> (require 'a)
Exception: {:error :assertion-failure, :data {:msg Cyclic load dependency: [ /a ]->/b->[ /a ]}}
clojure.core=> (require 'b)
Exception: {:error :assertion-failure, :data {:msg Cyclic load dependency: [ /b ]->/a->[ /b ]}}

Throws at the top level

➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/a.jank
(ns a)

(require 'b)
➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/b.jank
(ns b)


(throw "Hello")

➜  compiler+runtime git:(optimize/module-system) ✗ ./build/jank --module-path  /home/saket/Documents/oss/jank/compiler+runtime/dev/src repl
Bottom of clojure.core
clojure.core=> @*loaded-libs*
#{}
clojure.core=> (require 'a)
Exception: Hello
clojure.core=> @*loaded-libs*
#{a b}
clojure.core=>

With ns macro:

➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/a.jank
(ns a
  (:require [b]))
➜  compiler+runtime git:(optimize/module-system) ✗ cat dev/src/b.jank
(ns b)

(throw "Hello")
➜  compiler+runtime git:(optimize/module-system) ✗ ./build/jank --module-path  /home/saket/Documents/oss/jank/compiler+runtime/dev/src repl
Bottom of clojure.core
clojure.core=> (require 'a)
Exception: Hello
clojure.core=> @*loaded-libs*
#{b}
clojure.core=>
