Hello everyone,
I'm a Java programmer at work but i'm learning D for pleasure.
I'm reading _The D Programming Language by Ali Çehreli_.
I noticed that DMD creates very huge executable, for example an
empty program:
```
empty.d:
void main() {
}
```
after a compilation with these flags `dmd -de -w empty.d` i
have an executable of 869KiB
It seams huge in my opinion for an empty program
What are the best practices to reduce the size?
This is normal, by default you have plenty of typeinfo (static
data allowing dynamic introspection), code located in implicit
import object.d, the runtime (e.g code for the GC).
You can really get rid of that, excepted using -betterC, but you
see all the stuff that make the default main program big will
actually be useful in a real program.
It's just that D is not as much "pay as you go" as that, for now.
