Package macro-level
Description
Simply (:import-from #:macro-level #: from your defpackage. Don't macro-level)(:use)!
macro-level
macro-level is an embarrassingly trivial convenience macro
that saves on indentation while being more concise and direct.
(macro-level
...)
==
;; Canonical indentation. macro-level saves 11 spaces.
(macrolet ((m ()
...))
(m))
==
;; "Miser" indentation. macro-level saves 5 spaces.
(macrolet
((m ()
...))
(m))⚓
When used as part of a macroexpansion, macro-level also conveniently relieves the macro implementor from naming and using a gensym for the one-shot macro when compared to writing out a macrolet by hand, in addition to the other advantages.

Macro macro-level
&body body => results
Arguments and Values
- body -- An implicit progn.
- results -- The values of body.
Description
Expands to `(macrolet ((,macro () ,@body)) (,macro)) where macro is a gensym.
⚓
Support could eventually be added to Slime so that interactive macroexpansion of macro-level calls with C-c C-m (slime-expand-1)
would show the same expansion as interactively macroexpanding (m ...) after (defmacro m () ...), assuming the lexical context is not important.
