<P>

Two reasons.  Firstly, there are times when we want to be able
7
 
to trap orders to other people, which <TT>react_before</TT> does not.
8
 
Secondly, the player's <TT>react_before</TT> rule is not necessarily
9
 
the first to react.  In the case of the player's deafness, a cuckoo
10
 
may have already used <TT>react_before</TT> to sing.  But it would have been
11
 
safe to use <TT>GamePreRoutine</TT>, if a little untidy (because a rule about
12
 
the player would not be part of the player's definition, which makes
13
 
for confusing source code).  See <A HREF="section9.html">Section 9</A> for the exact sequence of events
14
 
when actions are processed.
