This is not obfuscation, but it might be useful and didn't quite fit anywhere else...
If you want to get every other item in a list or array, and don't care if the order is preserved, you can use this:

@a = keys   %{{@a}}    # for even indices
@a = values %{{@a}}    # for odd  indices

This is quite quick and powerful, but alas doesn't preserve the order.
