     43However, the issue prevents defining a constructor for such a generic-of-generic struct.  This declaration suffers from the same error.
     44{{{
     45forall( dtype T )
     46void ?{}( b2(T) & ) {}
     47}}}

     49A workaround for the constructor problem (which may often be hard to apply) is to make the b2 parameters sized.  This version compiles.
     50{{{
     51forall( dtype T | sized(T) )
     52struct b2 {
     53    a(T) aa;
     54};
     55
     56forall( dtype T | sized(T) )
     57void ?{}( b2(T) & ) {}
