 * When benchmarking, the three most significant var to tune are:
-  * `Memory::Global_BlockSize` (found gen_dep.hpp) : Used by the GlobalAllocator for the size of each global arena.

   * The default values can handled generating for a string up to a size of ~650 kbs (bottleneck is serialization).

 # TODO
 
-* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
+* Support defining & parsing full definitions inside a typedef. (For C patterns)
-* Make a more robust test suite.
-* Generate a single-header library.
-* Convert global allocation strategy to use the dual-scratch allocator for a contextual scope.
-* May be in need of a better name, I found a few repos with this same one...
 * Support module and attribute parsing (Marked with TODOs for now..)
+* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
 * Trailing specifiers ( postfix ) for functions (const, override, final)
+* Make a more robust test suite.
+* Generate a single-header library
+  * Componetize the library, make a metaprogram using gencpp to bootstrap itself.
 * Implement the Scanner
 * Implement the Editor
-* Support defining/parsing full definitions inside a typedef. (For C patterns)
-* Make the library bootstrap itself? It would make the code generated have less macros.
-  * Easier to tailor make the library for other projects.
-  * Most code can be in componentized into files and then scanned in.
-  * Can offer a more c-like version for the implementation, make namespaces optional, etc. (Good way to stress test it)
 * Should the builder be an "extension" header?
   * Technically the library doesn't require it and the user can use their own filesystem library.
   * It would allow me to remove the filesystem dependencies and related functions outside of gen base headers. ( At least 1k loc reduced )
+  * ADT and the CSV parser depend on it as well. The `str_fmt_file` related functions do as well but they can be ommited.
+  * Scanner and editor will also depend on it so they would need to include w/e the depency header for all three file-interacting interfaces.
+    * `gen.dep.files.hpp`
+* Convert GlobalAllocator to a slab allocator:
