It seems to me that we could allocate the String[] (or the C++
equivalent, really -- we don't need the object header) on the stack.
Since string concatenation behavior is largely known at compile time,
we can just have "tmp[slot] = <whatever>.toString()" directly
generated by the compiler.

Things like this could be handled specially as well, if we wanted to
be tricky.  We could allocate enough space on the stack for the
resulting character array and just use (our internal equivalent of)
sprintf.
