These above won't work, but the below will:

        $LOAD_PATH << "mydir"
        $LOAD_PATH.unshift "mydir"

Ruby distinguishes greatly between variables and the objects
they refer to.

In the former case, you're trying to make the variable refer
to a different object, which won't work for this variable.

In the latter case, you're altering the object to which the
variable refers.

Does that help?
