Question about the difference between `glob` and `GlobIterator` behaviour

Hello ! I’m currently working on the Hoa Project (http://hoa-project.net) about a glob behaviour integration: https://github.com/hoaproject/File/pull/22 We found that there are some difference between the glob function and the GlobIterator object. 1. glob This function is able to scan only dirs with the GLOB_ONLYDIR constant and is also able to expand braces to match in a list of items with GLOB_BRACE. Exemple with glob(‘/{a,b,c}/foo/bar’, GLOB_BRACE), it’ll search : - /a/foo/bar - /b/foo/bar - /c/foo/bar 2. GlobIterator This object has no options or constants to apply the same logic than GLOB_ONLYDIR and GLOB_BRACE. It’s possible to combine different iterators and obtain the same result but it’s a lot more complicated. Exemple with new GlobIterator(‘/{a,b,c}/foo/bar’), it’ll search : - /{a,b,c}/foo/bar Is there some reason about the differences in these two implementations ? I found that the braces expansion is not part of the “official” glob pattern definition but it’s definitively an awesome feature. Thanks in advance for your attention.
