A symbol macro is not a global attribute. Portable programs cannot make global variable,
function, ... definitions for exported CL symbols, but they may establish lexical bindings,
where such bindings cannot shadow a defined global binding.

Right. This code is in error.
The problem I was responding to however, was that the compiler for some implementation was
complaining about valid *lexical* bindings.
Note however, that it may or may not be that its a bad idea to use exported CL names for
these CLIM entities for the same reasons. I don't know enough about CLIM toknow the scope of
the names being defined as CLIM entities.
