They don't seem to actually be @safe. An example:

----
import cachetools.containers.lists;
import std.stdio;
void main() @safe
{
     DList!int dl;
     dl.insert_first(42);
     auto r = dl.range;
     dl.clear();
     writeln(r.front); /* Prints garbage, because it's accessing `free`d 
memory. */
}
----

As far as I can I see, that compiles because you have a bad @trusted 
here:

Other containers probably have similar problems.
