Two types need to know about each other

you can include a file in an include file eh..

include1.bmx:

include"include2.bmx"

codeblahblah
codeblahblah


include2.bmx:

include"include1.bmx"

codeblahblah
codeblahblah



But of course this is all prone to chaos if you ask me..

Actually I often bump onto the same situation, I'd like some more experienced programmers to comment on this issue as well.
