Is there a way to quickly display the return type of an un-annotated function?
e.g. (simple example) for `def isPalindrome (n: Int) = n.toString == n.toString.reverse` is there a quick way to get IDEA to tell me that this is a Boolean?
If I can find a usage of a function I can hover over it and hold Ctrl, but not so on the definition. If I hover and hold Shift it tells me it's a Function1 that extends Object (not very useful). Ideally I'd like just to hover the mouse over the function name to see the type like you get in Eclipse.
