happy that D has in the default lib functions like
levenshteinDistance, but this will not attract the average or
"just starting to learn" developer. On the contrary, sorting
correctly some names is a more common task than calculating
the Levenshtein distance, but there is no function for it in
phobos.
You may have a point that schwartzSort has a bad name (I
disagree), but putting another algorithm does not make the
documentation worse per se. Dunno, what problem you have with
the levenshteinDistance.
schwartzSort it's a nice name only if you are German. You got me
wrong, I have nothing against the function itself, nor against
the presence in the stdlib, but I play the role of the devil's
advocate and I try to walk in the D's new user shoes who's
expecting probably something more readable than 4 stuffed
consonants. Personally, I know what a Schwartz transform is and I
speak some German :)

What do you mean by correct? http://unicode.org/reports/tr10/?
From the link you posted:
"Collation is not aligned with character sets or repertoires of
characters.
Swedish and German share most of the same characters, for
example, but have *very different* sorting orders."
"We even have something obscure like levenshteinDistance but no
implementation for the unicode collation algorithm, which all
newcomers are looking for!" is a) a questionable comparison
between a relative simple algorithm and a monster and b) wrong,
because 99% of programmers don't even know about the algorithm
itself, thus they aren't looking for it.
I explained this in another topic regarding portability
obsession, it's a monster probably on Linux, on Windows/Mac it's
exactly one line of code, already done it:

BTW. python's startwith does the Köln example wrong. Kö and
Ko\u0308 dont match.
Today was my first contact with Python, I cannot comment on this,
may be Python is not aware of normalization forms and is not
combining o with the diaeresis (u0308).
