How define nested types ?

[NN]

This one doesn't work:

def a = typer.Env.Define(<[ decl: module A {} ]>);
a.Define(<[ decl: module B {} ]>);
a.Compile();

error : the type A.B was not finalized, forgot the TypeBuilder.Compile () on it?

This one compiles but creates only top module 'X' without nested A and B !!!

def x = [<[ decl: module A {} ]>, <[ decl: module B : A {} ]>];
def tb = typer.Env.Define(<[ decl: module X { ..$x } ]>);
tb.Compile();

Everything is simple you define types with DefineNestedTypes and members with Define.

Example:
def t = typer.Env.Define(<[ decl: module A {} ]>);
t.DefineNestedType(<[ decl: class B {} ]>).Compile();
t.Define(<[ decl: public F() : void {} ]>);
t.Compile();
