Slices, even empty ones, are assignable places in TXR Lisp: we can easily replace a possibly empty section of a string, lisp or vector, with a sequence that is of different length, also possibly empty: for instance, if <code>x</code> contains <code>"abc"</code> then <code>(set [x 1..2] "foo")</code> changes <code>x</code> to contain <code>"afooc"</code>.
