2 Loop Constructs
namedconstruct to name a loop so that the Common Lisp special form
return-fromcan be used.
finally loop keywords designate loop constructs that cause expressions to be evaluated before and after the loop body respectively.
The loop construct
initially causes expressions to be evaluated before any other clauses in the expanded form of
loop; if specified,
initially clauses lead the loop prologue. The construct
finally causes expressions to be evaluated after all other clauses in the expanded form; if specified,
finally clauses end the loop epilogue.
