Information hiding is far from being a central concern.  One thing is
that CL doesn't have a module system -- packages are only a namespace
management device.  You don't get seperate compilation, you cannot
parameterize code, you cannot override things and have the module
system do the right thing.  One indication of this weaknesses is the
silly solution of making it an error to override builtin bindings.
And the most major pain is that macros are a huge mess.
