I suspect that 'reverse returns the 'tail of the block, because to return
the 'head of the block could be wrong, if one is 'reverse-ing only part of a
block? For example:
>> reverse next x: [1 2 3 4 5]
== []
>> x
== [1 5 4 3 2]
Though I'm not sure why one would want to only reverse part of a block (or
series)?
