I'll be religiously avoiding "*unicode.IsUpper*()" as something mystery happened in the past: https://groups.google.com/d/msg/golang-nuts/714WQs85H3w/KEqKgmAqAAAJ
BTW, *for my case*, I do need the string, "FooBarBaz GNU PYTHON Standard" to be split exactly to be "Foo Bar Baz GNU PYTHON Standard" I.e., 6 words altogether, no more spacing than this. thanks again for helping and showing me you benchmark code.
