6.1.1.5.4 Summary of Unconditional Execution Clauses
The do (or doing) construct evaluates all forms in its clause.
The return construct takes one
form. Any values returned by the form are
immediately returned by the loop form.
It is equivalent to the clause
do (return-from block-name value),
where block-name is the name specified in a named
clause, or nil if there is no named clause.
For more information, see Section 6.1.5 Unconditional Execution Clauses.
