* fix: don't set the inner env to globals in type mods
Previously, we set the inner environment of a type generated module to
the global env in cases where the overarching context didn't have an
inner env. This leads to problems where by the recognition of modules is
inconsistent, and one can't use the names of types as submodules in
certain circumstances.
This commit fixes that issue.
* refactor: refactor primitiveDefmodule
This refactor fixes a issues with meta information on submodules, for
instance, sigs on submodule functions used to result in a compiler error
about ambiguous identifiers. This fixes that.
Unfortunately, I don't have a precise idea about what exactly was wrong
with the original definition of this function. My suspicion is that the
recursion originally altered submodule paths in the wrong way, but I'm
not certain. In any case it's fixed.
* fix: ensure macros are expanded in the correct module
Previously, macro expansions folded over all forms after the top level
form, without performing any context updates on encountered
`defmodules`. This created an issue in which macro calls that produced
new bindings, "meta stubs", were *hoisted* out of submodules and into
the top-level module, creating duplicate definitions.
This commit fixes that issue by adding a special case for defmodule in
macroExpand.
* fix: ensure submodules and globals don't conflict
Previously, our module lookups during new module definition always
eventually fell back to the global environment, which caused submodules
that happen to share a name with a global module to be confused with the
global module. This change fixes that, so now one can define both
`Dynamic` (global) and `Foo.Dynamic` without issue.
* fix: remove old prefixes from vector tests

Carp
WARNING! This is a research project and a lot of information here might become outdated and misleading without any explanation. Don't use it for anything important just yet!
Version 0.4 of the language is out!
About
Carp is a programming language designed to work well for interactive and performance sensitive use cases like games, sound synthesis and visualizations.
The key features of Carp are the following:
- Automatic and deterministic memory management (no garbage collector or VM)
- Inferred static types for great speed and reliability
- Ownership tracking enables a functional programming style while still using mutation of cache-friendly data structures under the hood
- No hidden performance penalties – allocation and copying are explicit
- Straightforward integration with existing C code
- Lisp macros, compile time scripting and a helpful REPL

A Very Small Example
(load-and-use SDL)
(defn tick [state]
(+ state 10))
(defn draw [app rend state]
(bg rend &(rgb (/ @state 2) (/ @state 3) (/ @state 4))))
(defn main []
(let [app (SDLApp.create "The Minimalistic Color Generator" 400 300)
state 0]
(SDLApp.run-with-callbacks &app SDLApp.quit-on-esc tick draw state)))
For instructions on how to run Carp code, see this document.
