I think you want to generate a different delegate for each element where 
the first argument to sg is the value of that element (0, 1, etc.). 
Since the second element of sg is a Props, you then want to call those 
delegates with a Props value (e.g. Props.p1).

The following works:

     import std.algorithm;
     auto mapped = indarr
                   .map!(a => (Props p) => sg(a, p))
                   .map!(d => d(Props.p1));

     writeln(mapped);
