In the get_integer_keyed_int method in perlarray.pmc, we're cuurently doing:
[Snip]
(with similar code for get_number_keyed_int and get_string_keyed_int).
In other words, if we're referencing an element outside the current array bounds, then we call undef(), which creates a new PerlUndef PMC, and we then use this _solely_ to call get_integer on, despite the fact that we _know_ that the result is going to be zero. This seems remarkably inefficient. Is there any good reason not to simply rewrite the above
Nope, though we do need to add a conditional use of undefined value warning. -- Dan
