Although there is no problem >> with this (fn [] 1). That's because #(1) expands to: user=> (macroexpand-1 '#(1)) (fn* [] (1)) but you don't want the parentheses around the 1. So for #(xxx), xxx needs to be a function. This is why something like #(do 1) or #(identity 1) works: user=> (macroexpand-1 '#(do 1)) (fn* [] (do 1)) user=> (do 1) 1 user=> (macroexpand-1 '#(identity 1)) (fn* [] (identity 1)) user=> (identity 1) 1 -- Michael Wood <esiot...@gmail.com> -- You received this message because you are subscribed to the Google Groups "Clojure" group.
