' '.join(sequence) tends to get some bad rep, but I think it's more OO
of the two. After all, general sequences should not have an operation
of "join elements with strings", because it doesn't make sense for
e.g. a sequence of sockets, while for a string it's reasonable to
provide an operation that joins a sequence of string with itself
(because it can expect the sequence to be that of strings).

That is, string can know about sequences, but a sequence, being a more
general data type, should not know about strings.

As far as FP goes, allowing t.split w/o () is extremely non-FP,
because you lose first class functions. And FP without first class
functions is, well, Java.
