I was looking at a list of Emacs' special forms, and noticed that
prog2 is implemented in C. Is there any interest in moving this to a
simple macro?
I don't have opinion about if this is worth or not, but i think is
safer to avoid the use of backquote: prog2 could be used in an
early stage of the bootstrap.
Instead of:
+ `(prog1
+ (progn ,form1 ,form2)
+ ,@body))
Better use:
(cons 'prog1
(cons (list 'progn form1 form2)
body)))
