Indexing the empty array with a string should MAYBE throw, or perhaps it should never throw? [4574] - Pike-devel

1 Sep 2008


      Indexing array(string-indexables) with a string works, indexing
array(non-string-indexables) does not. I don't see how that is a
problem, but maybe my pragmatism is broken.
(String-indexables being mappings and, likely, any kind of objects.)

           })
This seems a bit inconsistent.
