Mike and I have had a nice off-line conversation where we enumerated the possible things that can come after open-parens. I listed 7, he added 3: > 1. A value (if the paren has a tick '( ) > 2.

The anonymous function macro: #( ) So, at least I know why I feel uneasy about open paren! It's super overloaded. Mike also points out that things that aren't functions (not used in that context) can't be aliased with def or use. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
