I want my type to extend two types

Is there any way to make a type extend two different types, or do I have to arrange them in a stack, so that my type extends one type, which in turn extends the other type?

Nah you cant unfortunately :( A Stack is probably the best way to go.

The other option is to simply use composition. Extend from one type and have a field of the other type.

It is not mad, but it runs:

Strict

Type t1
	Field a
	Method geta()
		Return a
	End Method
End Type

Type t2
	Field b
	Method getb()
		Return b
	End Method
End Type

Type comb
	Global t1:t1 = New t1
	Global t2:t2 = New t2
End Type


Local my:comb = New comb

my.t1.a = 10
my.t2.b = 20

Print "> "+ my.t1.geta()
Print "> "+ my.t2.getb()

Or, which I make:

Strict

Type t1
	Field a
	Method geta()
		Return a
	End Method
End Type

Type t2 Extends t1
	Field b
	Method getb()
		Return b
	End Method
End Type


Type t3 Extends t2
	Field c
	Method getc()
		Return c
	End Method
End Type


Local my:t3 = New t3

my.a = 10
my.b = 20
my.c = 30

Print "> "+ my.geta()
Print "> "+ my.getb()
Print "> "+ my.getc()

do the above
