 Features
 
 - Made additional speed increases to `read`.
+- Streamlined type checking to make the `remainder` function faster.
 - Relocated `string-join` to `(scheme cyclone util)` and added a corresponding `string-split` function.
 - Allow optimization of `define-c` functions marked as `inline` even if an alternative non-CPS version of the function is not defined.
