If you're compiling with -property, filter must have the parens for the function call as it's a function, not a property. The !() is for the template arguments and is separate from the parens for the function call. That means that if you're compiling with -property and using UFCS, then you end up with range.filter!(pred)(), whereas you have range.filter!(pred). - Jonathan M Davis
