#### 6.1.1.11 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.
