What about adding this new binding syntax?
[(attrs map?) & contents] ; optional first map argument
[(attrs map? {}) & contents] ; with default value
[(s String)]
; is shorthand for
[(s #(instance? String %))]
; a function taking optional map, vector, string arguments.
[(m map?) (v vector?) (s String) n]
