Functions can be namespaced indeed. 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.
