They are publicly imported from std.uni

Those functions used to be in `std.string` a long time ago and 
are no more. As did some others. The section where you found them 
in the `std.string` docs is a table listing their current 
location in `std.uni` and links to their documentation. It also 
says this just above the table:

 The following functions are publicly imported:

This means if you are already importing `std.string`, you do not 
need to import `std.uni` for `toUpper` and `toLower`, as 
`std.string` publicly imports them, so they will be available for 
you to use. So you can use those functions by importing 
`std.string` or `std.uni`.

They are usable though `import std.string;` the docs just don't 
do a great job showing that.

The newest test version of my doc generator does integrate them 
into the member list though:

http://dpldocs.info/experimental-docs/std.string.html

My dpldocs.info website has a search engine too to help find the 
original place:

dpldocs.info/toLower

for example will point you at std.uni first.

But if it is "public imported" into a member list of another 
module you can use it just importing either way.
