I've done some major updating of my Plot2kill plotting library lately,
I see code that wants named arguments :-)
65 auto sleepinessFig = Figure(sleepinessPlot)
66 .title("Sleepiness Survey")
67 .yLabel("Sleepiness Rating")
68 .xLabel("Activity")
69 .legendLocation(LegendLocation.right)

Bye,

Why? Each of those arguments should be able to be set after creation.
So given DRY principals, method chaining is the way to go. Besides,
Figure takes a variable number of plot arguments, which means you
couldn't support default arguments (at least with the current syntax).
The funny thing is what will happen to this code once @property is
properly implemented? I think this is a cleaner way to write the above,
and it'll work with @property:
auto sleepinessFig = Figure(sleepinessPlot);
with (sleepinessFig) {
title = "Sleepiness Survey";
yLabel = "Seeliness Rating";
xLabel = "Activity";
legendLocation = LegendLocation.right;
horizontalGrid = true;
xTickLabels(iota(3), ["In meeting, "On Phone", "Coding]);
}
