There are two causes of this:<br>
<br>
1. Typeinfo getting larger, and people wanting more features in
Typeinfo (like precise gc) so this will continue to increase.<br>
<br>
2. Every phobos module imports and relies on every other one.<br>
<br>
<br>
To find out why .o files are large, run obj2asm on it. To find out
why executables are large, compile with the -map switch and examine
the linker .map file. <rant>AFAIK, I'm the only person who
ever does this.</rant><br>
<br>
Please, everyone. Once in a while, run obj2asm on the library module
you're developing and have a look-see at what is coming out of the
compiler.<br>
