Why does the example on page 8 of TDPL work without importing std.algorithm for splitter?

Thanks now I understand, this also means that the example on page 8 only 
works because of bug 314, and should this bug ever be fixed then the 
example code will break. Therefore it really should include an import of 
std.algorithm explicitly for both clarity and long term reliability.
