How about keyword parameters...
ctx.arc(center=Point(10,20), radius=30, beginAngle=0, endAngle=6.28, Clockwise);
...and don't forget about units of measurement/dimensional analysis.

ctx.arc(center=Point(10cm,20cm), radius=30mm, beginAngle=0rad, endAngle=6.28rad, Clockwise);
- buffyoda 10y agoThat helps quite a lot, although for several, it's more programming-by-name than programming-by-semantics. I'd like to be able to say the end angle has to be less than the start angle, that the unit has to be radians (AKA unit-less :), the unit of radius & that negative values are sensical, and so forth; and have all these properties checked by a compiler. Which I can do in some modern languages, surprisingly. :)
- lomnakkus 10y agoAssuming you're right about the guesses for those parameters, we could go a little further. Let's define data Directionality = Clockwise | Anticlockwise data AngularInterval = { beginAngle :: Double, endAngle :: Double, directionality :: Directionality } ... and then we're down to three parameters, all of different types (so no opportunity for mistakes, assuming static checking) and who knows, you might even have other uses for AngularInterval.
