No, it must be that way. Inside build() var is defined as the variable
that is defined in the interface. build() has no way to see the variable
outside it because it can only find the inner name. It could reference
it's value if you had passed the value or it could reference the variable
by name if it would not be hidden by your interface variable.
int a = 2;
int build(int a)
{
return a;
}
int b = build(42);
b will be 42.
