I'm sure this is straightforward enough, but for some reason I can't wrap my brain around an elegant solution. I have a hash that has keys of (100, 101, 102, 103, 104, 105, 106, 107). I'd like to remove some number of elements starting with some other arbitrary element. For example, 3 elements, starting with the 2nd (101, 102, 103). This is easy enough to compute with an array, since they're indexed on number, but I'm not sure how to do it with a hash.

The ugly way would be to create a parallel array that has the sorted keys of the hash, then foreach over a slice of that array and delete the appropriate hash elements. But surely there's a more elegant way, yes?
