Re: Looping through an array with FOR EACH

[Brian G <brian@xxxxxxxxxxxxxxxx>]

I think here we have have Ben step in, because what you are all stating 
is that 'for each' is a totally unreliable way of for instance
listing a newly sorted array of strings... even the hint of a 'maybe not 
work'  in a production environment is not acceptable on any level.
I just don't believe for simple arrays that Ben would allow such a 
bug/instability to persist as part of such an amazing work!

If this is on any level true, perhaps this construct should be removed 
from the language it is therefore a useless construct.
No body should be afraid to use a tool as intended.
