It is really just personal preference, people tend to leave the 
parens off when they just add subjective noise. A good rule 
though would be to leave the parens off when it is an obvious 
function call or if the function is cheap enough that the call 
doesn't matter (if it is just a thin property for example).

basically yeah it is just that.
