Be careful with the (filter identity ...) which will also remove "falses" from seqs. (filter identity [nil 2 3 nil false true 4]) => (2 3 true 4) Since (identity false) and (identity nil) returns respectively false and nil they are BOTH rejected by filter.
This could do the trick: (filter (comp not nit?) [nil 2 3 nil false true 4]) => (2 3 false true 4) On Wednesday, November 17, 2010 2:37:16 AM UTC+1, Luc wrote: > user=> (time (filter identity [ nil 1 2 nil 4])) > "Elapsed time: 0.053219 msecs" > (1 2 4) > > user=> (time (remove nil?
