Just to clarify. In the example above, if I create a 'BTree!int'
by itself, it's fine. If I create a 'BTree!char' by itself, it's
fine also. But if I create both, even if they are created in
different modules, the compiler seems to mix up the types of the
function template-parameter, and tries to fit a 'char' to the
'int' function or an 'int' to the 'char' function, depending on
which was declared first.
