Isn't it bad to refer to BODY twice?
It is not bad if only one of them will be executed in any given
execution of the macro expansion. It is a little wasteful,
but that's not worth worrying about here.
>From the manual:
@node Argument Evaluation
@subsection Evaluating Macro Arguments Repeatedly
When defining a macro you must pay attention to the number of times
the arguments will be evaluated when the expansion is executed.
