   	Class.Method1 m1 = new c.Method1();

}

i just try to write an simple oop-wrapper for an method
but i get this compile error:

"nested.d(29): no 'this' for nested class Method1"

from the d-docs
"A non-static nested class can only be instantiated when the necessary context pointer information is available"

i think there "is" a contex avaiable (through "c")

how can i solve the problem?

thx dennis

The compiler must know in which context the nested class should be created.

The context has to be available as the current this.
You can only instanciate the nested class in this way from within a method of
the outer class.

in the contex of "c"

i don't understand why d can't see the contex in "new c.Method1"
c is the outer object(the contex) and Method1 is the inner class

wouldnt it be nice to have such a feature?
