   > 2\. Allow to specify the `occurence` keyword, given that this is not necessarily obvious, it's nice to be able to specify the named argument:
   
   Actually, that errors only because I mis-spelled the keyword name. With the correct name it works:
   
   ```
   >>> pc.map_lookup(arr, pa.scalar("a"), occurrence="all")
   <pyarrow.lib.ListArray object at 0x7f099c96bd00>
   [
     [
       "a1"
     ],
     [
       "a2"
     ],
     [
       "a1"
     ]
   ]
   ```
   
   Wondering if we can provide a better error message in that case, but that might just be a Python/cython behaviour of first checking the positional keywords before the named ones)
