Better yet, create a file called something like common.d containing
public imports of everything you want to share across files, and just
import it at the top of each file:

	// common.d
	module common;
	public import std;
	public import;

	// in each file:
	import common;

Or, if you want to be able to switch out the common import dynamically,
you could use this trick I recently invented: add this to the top of
every file:

	import __stdin;

then run your compile command with:

	echo 'public import std; public import whatever.else;' | dmd - mysources.d ...

Then you can inject arbitrary D code into your project via the command
