[Haskell-cafe] Prefix/Infix operators

2006-07-07 Thread Sara Kenedy
Hello everybody, I checked the topics in Haskell-Cafe about prefix/infix operators but I did not find them. Now I bring my questions to here to ask you. 1) I have a Common-Lisp code representing an expression result as follows ((MPLUS SIMP) ((MTIMES SIMP) ((RAT SIMP) 1 2) ((MEXPT SIMP)
