Immutable array initialization in shared static this

[Era Scarecrow]

  When you use the length property it allocates space and assigns 
it to the immutable array. the array now contains data (10 0's). 
You've said you won't change any data in it's declaration but the 
array itself can be changed (appending or a different array).

  I would think the best solution is to create a mutable local 
version, and then assign the immutable global one when you are 
done. If the array is particularly short (Like your example), 
then appending will work fine for your values (unless you mutate 
the array as part of it's calculation, then a local copy is 
required).
