The "&" form is a syntax helper. In other words it is intended to change the source code, not to change the way you program. Thus you have to look at the intended use of the function. If you are going to type different number arguments to a function right in the code yourself, then use &. If you are going to get the arguments for that function at runtime, then use a single argument. Examples: map, filter, reduce. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
