(no) circular dependency

Hi Mark,

Uhm... sometimes this is not always possible.
For example I have a package QCA which produces truth tables (all
combinations of presence / absence of causal conditions), and it uses the
venn package to draw a Venn diagram.
It is debatable if one should assimilate the "venn" package into the QCA
package (other people might want Venn diagrams but not necessarily the
other QCA functions).

On the other hand, the package venn would like to use the QCA package to
demonstrate its abilities to plot Venn diagrams based on truth tables
produced by the QCA package. Both have very different purposes, yet both
use functions from each other.

So I'm with Bill Dunlap here that several smaller packages are preferable
to one larger one, but on the other hand I can't separate those functions
into a third package: the truth table production is very specific to the
QCA package, while plotting Venn diagrams is very specific to the venn
package. I don't see how to separate those functions from their main
packages and create a third one that each would depend on.

This is just an example, there could be others as well, reason for which I
am (still) looking for a solution to:
- preserve the current functionalities in packages A and B (to follow
Dmitri's original post)
- be able to use functions from each other
- yet avoid circular dependency

I hope this explains it,
Adrian
