I have one minor comment about join. You should specify its behavior when
it is passed an empty list. Does it return undef or the empty string?
I think it makes the most sense for it to return an empty string,
which is a reasonable degenerate case of a string-join. -- Darren

Or to put it another way, I see string-join being like a prefix
version of the ~ operator (though with extra features), and so the
reduce rules of ~ should perhaps determine it. According to Synopsis
3, "[~]()" returns the empty string. -- Darren Duncan
