I’m referring to another thread where I brought an example with Collection::map and array::map. You can easily define those as functions in different namespaces, but when it comes time to use it, you’ll likely end up having to use the same function name in a single file. It’s then one of three options: 1) you don’t import your functions, leading to ugly long calls: \Illuminate\Collection\map(…, fn () ..), \Some\Vendor\Arrays\map(…, fn () ..) 2) you do import your functions, but end up aliasing: use function Illuminate\Collection\map as collection_map;, use function Some\Vendor\Arrays\map as array_map; 3) you define your functions with prefixes from the beginning, just to avoid having to manually alias them all the time: use function Illuminate\Collection\collection_map; All of the solutions are far from perfect. I apologize if I’m missing something.
