I'm trying to identify the preferred ways to lower case a string.
In std.uni there are two functions that return the lower case
form of a string: toLower() and asLowerCase(). There is also
toLowerInPlace().
I'm having trouble figuring out what the relationship is between
these, and when to prefer one over the other. Both take a
strings, asLowerCase also takes range. Otherwise, I couldn't find
the differences in the documentation. Implementations are
apparently different, but not clear what the real difference is.
Are there reasons to prefer one over the other?
