I was experimenting with `--gc-sections` effect on D code (with
great results) and have noticed that GDC binaries are much bigger
than DMD ones. I do understand that it is not a priority goal
right now but still curious, does anyone know what makes such
notable (~50%) difference?

import std.stdio, std.algorithm;
void main()
{
auto arr = [ 1, 2, 3 ];
writeln( arr.map!( a => a*2 )() );
}
