Ok, but now I'm getting these error in my new 
mypackage/constants.d

..\common\vertex_data.d(5,15): Error: undefined identifier 
'GLfloat'
..\common\vertex_data.d(53,12): Error: undefined identifier 'vec3'

Is there a way to just suck in the text from say a .txt file that 
would not be compiled before inclusion in main.d?
