I'm kinda surprised we allow any further modifications in the presence of eval.

eval is used by some libraries, so I thought we should only give up if it's going to be problematic. (e.g. name mangler aborts)

But I'm not sure about this. Do you think it's better to abort completely on eval?

Personally, yah, I would. Looking at terser, eval deopts:
- name mangling
- unused var removal
- joining of expressions
- inlining functions
- conversion from functions/methods to arrows

Did it and checked other passes, too. Thank you!
