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);

Yes exactly!
The idea is to save
auto mapped = indarr.map!(a => (Props p) => sg(a, p));
for later use and use it then
by mapped[someIndex](Props.p1) or mapped[someIndex](Props.p2)
when needed.
Thank you very much! :)
