Returns the same result for [] and {}

Hi @jcward, not too sure about this one. I agree if stringify'ing a hash then returning 'Array' is misleading, but I don't think this is main point of this. Stringify is used to just turn any object into a string. When you use sort on a hash you get an array back anyway, but that is another point.

Are you currently using stringify and need 'Hash' returned? If you need the type then I'd use {}.class which would be accurate.

I would make the stringify method private to allow the signature method only, but people might be consuming the stringify method now. If there is a need to specify Hash when using an original Hash then this can be looked at, but there is a reason why turning the Hash into an Array is implemented.

I'm just using stringify because it's easier to see what's happening under the hood than signature's hex output. Their equivalence is interchangeable (having the same string == having the same signature).

The jist of this issue is that Crimp considers [] the exact same as {} -- maybe that's the intent. Also, [{}] is the same as [[]], and {:foo=>[]} as {:foo=>{}}.

This issue is more about letting people know what they're getting with Crimp. Feel free to close as "as-designed".

For me, I expected a unique signature per any object I input. I wouldn't think [] == {} so I was surprised.
