Is this out of scope? Surely we can at least have some way of dealing with c++ features like casts and classes and certain c99 inherited features.

Possibly by adapting it for capstone in order to generalize other targets like ARM (GBA decomp, etc).

Change types of literals

2 vs 2U vs 2.0f vs 2.0 can give similar but slightly different codegen. Should be done in a random region, ideally

Using randomization passes made especially for the purpose. E.g. ones that throw away unnecessary `if(1) {}` and expand vars with name `new_var*`.

Sometimes start from found improvements

Combining improvements would be a later step.

The latter does not obey the triangle inequality -- making a function match worse can improve the score by breaking parts that are accidentally the same between source/target and thus...

Currently in the randomization code we track node locations by traversing the AST in preorder, and giving every node an index. We should extend that to record every node's start...
