I really like the functional style of Julia as I primarily code in OCaml. One of the cool optional features of the OCaml compiler is that if you define a function and a variable is unused, the compiler will complain that you have a variable that was never used. I'm surprised how many bugs have been caught by this functionality, and I have already been bitten twice by this bug in Julia in my 1st week of using it!
Is there a chance we will get the ability for the compiler to complain about unused variables? - Ben
