Steve, are there not several (probably better, faster) alternatives to 
the built-in AA that are nothrow? I think a nice way to look at the 
built-in AA is an easy default for quick scripts, new users, etc., much 
like the default of `throw` status of a function or code block.

Advanced users, (i.e. those using nothrow annotation) could select a 
more efficient AA implementation anyway.
