This is why I don't want to see @property fully implemented. Ever. I
love this method chaining stuff and you can pry it out of my cold, dead
hands. There was a discussion about this a long time ago when I was
writing the first version of Plot2kill that gave me the impression that
@property was to be used for disambiguation only. (See
http://www.digitalmars.com/d/archives/digitalmars/D/Overloading_property_vs._non-property_113421.html
.)
The problem with the with statement idea is that you still need to
declare the variable. I often throw up quick anonymous plots with
anonymous Figure objects, like:
Histogram(someDataSet).toFigure
.title("A Title")
.xLabel("Stuff")
.showAsMain();
I consider the ability to have the same function be called with both
syntaxes to be a beautiful thing, not a defect. If @property is ever
fully implemented, I'll nag for an @optionalproperty tag to bring back
this **feature**.

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)

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]);
}
