Looking at the code as a whole, we ended up with a little to much "buttons". It turns out that doing case insensitive matching (lower both pattern and strings to match) performs just fine. Or at least, it gives the penalty to the people who uses mixed case filenames. ``` GetGlob/Default_cache-10 10.6ns ± 2% 10.6ns ± 1% ~ (p=0.657 n=4+4) GetGlob/Filenames_cache,_lowercase_searchs-10 10.6ns ± 2% 10.6ns ± 0% ~ (p=1.000 n=4+4) GetGlob/Filenames_cache,_mixed_case_searchs-10 29.7ns ± 1% 29.6ns ± 1% ~ (p=0.886 n=4+4) GetGlob/GetGlob-10 13.7ns ± 1% 13.7ns ± 0% ~ (p=0.429 n=4+4) name old alloc/op new alloc/op delta GetGlob/Default_cache-10 0.00B 0.00B ~ (all equal) GetGlob/Filenames_cache,_lowercase_searchs-10 0.00B 0.00B ~ (all equal) GetGlob/Filenames_cache,_mixed_case_searchs-10 5.00B ± 0% 5.00B ± 0% ~ (all equal) GetGlob/GetGlob-10 0.00B 0.00B ~ (all equal) name old allocs/op new allocs/op delta GetGlob/Default_cache-10 0.00 0.00 ~ (all equal) GetGlob/Filenames_cache,_lowercase_searchs-10 0.00 0.00 ~ (all equal) GetGlob/Filenames_cache,_mixed_case_searchs-10 1.00 ± 0% 1.00 ± 0% ~ (all equal) GetGlob/GetGlob-10 ```
