-  * Get rid of Scratch, move that concept onto the main context, create scratch memory from user allocator

-  * Reset compiler
+  @! Clean way to free all memory and reset the compiler
+  @! Bring the Table<>
+  @! Look into List, check if that's neccessary
 
+  @! Compute time statistics inside context and expose them properly

+  Probably want to implement a Red Black Tree then
+  probably I wouldn't need any sort of heap based
