It depends entirely on what you're trying to do. If you understand how
manifest constants work, then they can be quite advantageous. What you
probably really want for arrays though is not an enum but just a const or
immutable module variable.
immutable a = [3, 1, 2];
Otherwise, you're allocating a new array every time you use the enum.
So, use
a manifest constant when you want to avoid having it take up any memory
but
don't care about whatever allocations may occur when it's used (primitive
types such as ints being a prime example), whereas if you want an actual
memory location for the constant and/or want it to be allocated only
once,
then use variable rather than an enum.

Wait a second, it is definitely a bug. You can't modify an enum.
"immutable a = [3, 1, 2];" is practically "enum a = [3, 1, 2];".
