V/HLayout inside StackLayout

Questions
1

Hi, I’m trying to create a StackLayout with a VLayout inside, but the following code just creates an empty window:

(
w = Window()
.layout_(
	StackLayout(
		VLayout(StaticText().string_("A"), StaticText().string_("B")),
		VLayout(StaticText().string_("C"), StaticText().string_("D"))
	)
)
.front;
)

I would have expected that StackLayout can be combined in the same manner as VLayout with HLayout:

(
w = Window()
.layout_(
	HLayout(
		VLayout(StaticText().string_("A"), StaticText().string_("B")),
		VLayout(StaticText().string_("C"), StaticText().string_("D"))
	)
)
.front;
)

This seems to be a documented limitation of StackLayout:

StackLayout.new( … views)

Creates a StackLayout and fills it with the items given as arguments. The first view becomes the current one, i.e. visible and on top of others.

Arguments:

… views A sequence of views. Unlike other layouts, StackLayout can not contain another layout.

As long as your layouts are contained within views you can add them to the StackLayout

(
w = Window()
.layout_(
	StackLayout(
        View().layout_(VLayout(StaticText().string_("A"), StaticText().string_("B"))),
        View().layout_(VLayout(StaticText().string_("C"), StaticText().string_("D")))
	)
)
.front;
)
