2.13 Dispatch: case
Evaluates val-expr and uses the result to select a
case-clause. The selected clause is the first one with a
datum whose quoted form is eqv? to the
result of val-expr. If no such datum is present, the
else case-clause is selected; if no else
case-clause is present, either, then the result of the
case form is #<void>.
For the selected case-clause, the results of the last then-body, which is in tail position with respect to the case form, are the results for the whole case form.
A case-clause that starts with else must be the last case-clause.
