I don't know enough about linguistics to express this properly, but I
suspect there's something to be said about the "verb phrase" being the part
that comes before the paren. To me,
"comparePositionInDecodeOrderWithPosition(of:)" is confusing because there
is a noun "Position" immediately preceding the parenthesis, which might
indicate that the argument should be a position, but in reality the most
meaningful part of the method name is the verb, "compare".
