Guile complains about duplicate bindings in let or letrec, but not
let*; the second binding simply shadows the first.  I believe that's
what R5RS specifies.  (So it is possible to accidentally shadow an
existing binding, which may cause trouble in subsequent code similar
to set!.)

There are other forms of side effects, like I/O.
