+- [x] Print out all failed tests in a list at the end

+- [ ] Use unix (posix? bash? ascii?) color codes for errors
+- [ ] Print golden file as green and new output as red
+- [ ] Rename to Ink.jai
+- [ ] Add -test option. -test does the same as test.exe used to do
+- [ ] Add -fuzz option to run fuzzer (add args later)
+- [ ] Add -output option to output the compiled file. Issue with this is the generated data can't be output like that. Would require serialization.

+/* TODO
+- [x] Remove builtin stringbuilding and replace it with ad-hoc string building when error reporting. In that case we are already building a string anyway, so we can just pass in the string builder
+- [ ] Support structured buffers (ro, rw, w)
+- [ ] Support mesh and amplification shaders
+- [ ] Support compute shaders
+- [x] Support #if at top level
+- [x] Support #if at block level
+- [x] Remove properties block and just use hinted constant buffers instead
+     ```
+     props :: constant_buffer @properties {
+          [...]
+     }
+     ```
+- [ ] while loops
+- [ ] for-each loops
+- [ ] add parameters to hints (meta properties, resource binding indices if needed)
+- [ ] consider @entry(stage) syntax instead of the forced keyword
+- [ ] Add flags to compiler
+	- [ ] Generate output flag(s)
+	- [ ] Possibly final stage flag, so you can just call compile_file and it only does what you need. 
+		- Probably this flag is about which stage you need as the _last_ and not which stages to do, as that doesn't make sense.
+	- [ ] Multiple output languages?
