> a REPL. Just give it a whirl and see what you get. A REPL is in no-way tied to having a dynamically typed or interpreted programming language. E.g. Haskell's GHCi has an excellent REPL environment where you can, in addition to evaluating code, ask for the type of an expression and do other static analyses. I agree that a REPL makes a huge (mostly positive) difference on how you write code.
