Hi @stevehu

Thanks a lot for considering this PR and merging it.

Sorald (the tool that made this patch) is a part of a research project on automatic program repair.

We would be very happy to hear from you regarding any of the following topics:
1- The PR description: Was it explanatory enough? Did it have appropriate length? Did you prefer it to include some other information? ...?
2- The changed code: Did it have an appropriate style? ...?

We would also appreciate any other comment that you think it can help us to make Sorald a better tool.

Best,

[stevehu]

@khaes-kth This is a very good tool and it would help a lot of open-source projects. The PR looks pretty good and easy to understand with a detailed description. I like the reference links if users want to explore the extra details.

Regarding the coding style, I found the first file has some indentation issues with some extra spaces. Other than that, looks good.

Again, thanks a lot for your help.
