 Similar to {{case}}, but signals an error if no clause matches.
 
+<macro>(ensure PREDICATE EXP [ARGUMENTS ...])</macro>
+
+Evaluates the expression {{EXP}} and applies the one-argument
+procedure {{PREDICATE}} to the result. If the predicate returns
+{{#f}} an error is signaled, otherwise the result of {{EXP}}
+is returned.  If compiled in ''unsafe'' mode (either by specifying
+the {{-unsafe}} compiler option or by declaring {{(unsafe)}}),
+then this expression expands to an unspecified value.  If specified,
+the optional {{ARGUMENTS}} are used as arguments to the invocation
+of the error-signalling code, as in {{(error ARGUMENTS ...)}}. If
+no {{ARGUMENTS}} are given, a generic error message is displayed
+with the offending value and {{PREDICATE}} expression.
+
+<macro>(eval-when (SITUATION ...) EXP ...)</macro>
+
+Controls evaluation/compilation of subforms. {{SITUATION}} should
+be one of the symbols {{eval}}, {{compile}} or {{load}}.
+When encountered in the evaluator, and the situation specifier
+{{eval}} is not given, then this form is not evaluated and an
+unspecified value is returned.  When encountered while compiling code,
+and the situation specifier {{compile}} is given, then this form is
+evaluated at compile-time.  When encountered while compiling code, and the
+situation specifier {{load}} is not given, then this form is ignored
+and an expression resulting into an unspecified value is compiled instead.
+
+The following table should make this clearer:
+
+<table>
+<tr><th></th><th>In compiled code</th><th>In interpreted code</th></tr>
+<tr><td>{{eval}}</td><td>ignore</td><td>evaluate</td></tr>
+<tr><td>{{compile}}</td><td>evaluate at compile time</td><td>ignore</td></tr>
+<tr><td>{{load}}</td><td>compile as normal</td><td>ignore</td></tr>
+</table>
