Unfortunately this doesn't work as I'am trying to assign value 
from ctor to member something like:

this(%s value){
     this.value=value;
}

it gives me
Error: memcpy cannot be interpreted at compile time, because it 
has no available source code.
Probably this is caused by declaration of member which is also 
parametrized with T...
Member is:
Algebraic!(T) value;

So declaration of this mixin constructors are done before 
variable value is declared (compilation)?

Is there any field in class that would contain ctors ? Something 
like __ctors ?
i could try to init this(T... value) constructors in static 
constructor using delegates/functions. Something like:

template Outer(T...){
class Inner{
		Algebraic!(T) value;

		alias ctor(Type) =Inner delegate (Type value);
		static this(){
			foreach(Type;T){
				ctor!(Type) c={
					this.value=value;
				};
                         __ctors~=c; // ?????
			}

		}

}
