If all the following lines go together as a group, and the arguments on the first line aren't part of that group, then I'll indent the following lines differently to emphasize the grouping:
(each (k v) mytable
(prn "my key is " k)
(prn "and my value is " v))
It doesn't matter to me whether it's a macro or a function:
(copy (obj a 1)
'b 2
'c 3)
I use the two space indentation a lot more with macros than I do with functions because many macros use the pattern of some arguments followed by a body and not many functions do, but I don't change my indentation depending on whether it's a function or a macro.
If the lines after the first line don't fall into their own group, then I'll line up the arguments:
(+ '(a b c d)
'(e f g h)
'(i jk))
(map (fn (x) ...)
(generate-my-list ...))
For me the important consideration is using indentation to show which arguments go together.
