A lot of cases of the "noise" cases of `similar_names` come from two idents with a different first letter, which is easy enough to differentiate visually but causes this lint to be raised. Do not raise the lint in these cases, as long as the first character does not have a lookalike. Link: https://github.com/rust-lang/rust-clippy/issues/10926
