be specified to act on the base side using the <code><strong>base when</strong></code> keywords.
Within such a base guard predicate <code>base</code> is interpreted as a special identifier
holding a reference to the base object that is about to be lifted
for the sake of a callin method interception (see <a href="s5.4.2.a.html" title="&sect;5.4.2.(a)&nbsp;Base object reference"
