Yeah, this part bothers me too. Once I hacked up a script

little D program :P) that disassembles D executables and

and was quite dismayed to discover that the mere act of
importing
std.stdio (for calling writeln("Hello World");) will introduce
symbols
from std.complex into your executable, even though the program
has
nothing to do with complex numbers. These symbols are never
referenced
from main() (i.e., the reference graph of the std.complex
symbols are
disjoint from the subgraph that contains _Dmain), yet they are
included
in the executable.
Do you have any idea why the std.complex symbols were pulled
in, i.e. what dependencies were responsible? The only module
that I'm aware of that imports std.complex is std.numeric,
which is itself only imported by std.parallelism and std.random.
Are you sure it's not just the whole of Phobos being built in
statically because you don't strip the binary?
std.stdio -> std.algorithm -> std.random -> std.numeric ->
std.complex.
