Semicolons are not necessary after function definitions or control flow blocks, and having some code use them makes things inconsistent (and occasionally can mess up `clang-format`'s formatting). Removing them is tedious work though, I had to do this manually (regex + manual review) as I couldn't find a tool for that. All other code folders would need to get the same treatment.
