confused with data types

[thorstein]

Hello,

This was my goal:
-----------------
public double[][] skalar_m_2d(double[][] array, double skalar)
{
   return array.map!(b => b[].map!(c => c * skalar));
}

!!! But: return value is not double!

Type check for return value:
----------------------------
a = array.map!(b => b[].map!(c => c * skalar))
writeln(typeof(a).stringof); //-> MapResult!("__lambda4, 
double[][])

a = array.map!(b => b[].map!(c => c * skalar))[1];
writeln(typeof(a).stringof); //-> MapResult!("__lambda2, double[])

How can I get the result as double[][] ???

Thanks, thorstein
