So, I create a big hash full of lots of default values. (Imagine a big hash anyway) 
my %bighash = (
     'A' => 1,
     'B' => 2,
     'C' => 3
);

... and for some reason or other, I need to change a value or perhaps even add a completely new one ... 
$bighash{'C'} = 'some new value';
$bighash{'D'} = 4;

[download]
... which is no big deal when its isn't huge. Anyway, will the following ALWAYS do what the casual observer might expect (ie. replace the values of %bighash with the new ones)? Or is it possible to some versions of perl on some machines may sometimes repopulate %bighash backwards or in no particular order resulting in the changed keys to possibly be changed? 
%bighash = ( %bighash,
     'C' => 'some new value',
     'D' => 4
);

Or is there an even simpler, better, more obvious way to "bulk" append a hash and save a few keystrokes that I'm clearly missing? This technique seems to work, but I suppose that I'm looking for a communal blessing of sorts.
