Assume we are defining a macro then copy it via a \let into a second macro with something like


If we now want to now have tokens representing the invocation of this macro, we should then be able to use


which we would expect to return a single T_CS('\othermacro'). When running this code however, we get T_CS('\dummymacro') instead.

This comes from a more complicated scenario I encountered while updating keyval bindings, but I have gotten it down to this very basic example. This caused an infinite loop, making debugging very hard.

This should be fixed now; thanks for the report!
