If you are also interested in speed, then of the three solutions I
have seen proposed (flatten, stringize, stringit) flatten is the
clear winner (I timed it on some bigger list at 2.6s vs 6.0s vs 12.1s).

For the semantics you might want to use
string.join(flatten(thatbloodysequence))

P.S.: flatten wins because it constructs a list and not hundreds
      of immutable strings. stringit is bad because it uses
      lisp-style car-cdr recursion (very inefficient when used
      with python lists).
