ProcessMethodBodiesWithDuckTyping

The ProcessMethodBodies step does a tremendous amount of work.

One of the things it does is handle when you set properties by passing them to the constructor, using the builtin __eval__ function.
Also adding an event handler (Click += OnClick) is transformed into a method call (add_Click(OnClick)).
Closures are duplicated into a regular method. These are processed more in later steps.

See this example:

import System.Windows.Forms from System.Windows.Forms

[Boo.Lang.ModuleAttribute] public final transient class TempModule(System.Object):

private static def Main(argv as (string)) as System.Void:
	f = Form()
	clickcount = 0
	b = Button(Text: 'Hello', Dock: DockStyle.Fill)
	b.Click += { print("you clicked me ${(++clickcount)} times") }
	f.Controls.Add(b)
	f.ShowDialog()

private def constructor():
	pass

is transformed into:

import System.Windows.Forms from System.Windows.Forms

[Boo.Lang.ModuleAttribute] public final transient class TempModule(System.Object):

private static def Main(argv as (System.String)) as System.Void:
	f = System.Windows.Forms.Form()
	clickcount = 0
	b = __eval__(
                 (___temp1 = System.Windows.Forms.Button()), 
                  ___temp1.set_Text('Hello'), 
                  ___temp1.set_Dock(System.Windows.Forms.DockStyle.Fill), 
                  ___temp1)
	b.add_Click(
             { Boo.Lang.Builtins.print("you clicked me ${(clickcount = (clickcount + 1))} times") })
	f.get_Controls().Add(b)
	f.ShowDialog()

private def constructor():
	super()

internal static def ___closure2() as System.Void:
	Boo.Lang.Builtins.print(
              "you clicked me ${(clickcount = (clickcount + 1))} times")
