/*
 * From:

 * http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/aspectj-home/doc/progguide/semantics-declare.html#d0e6499
 *
 * Pointcuts that appear inside of declare forms have certain restrictions. 
 * Like other pointcuts, these pick out join points, but they do so in a 
 * way that is statically determinable. 
 * 
 * Consequently, such pointcuts may not include, directly or indirectly 
 * (through user-defined pointcut declarations) pointcuts that discriminate 
 * based on dynamic (runtime) context. Therefore, such pointcuts may not be 
 * defined in terms of
 * 
 * cflow
 * cflowbelow
 * this
 * target
 * args
 * if
 * 
 * all of which can discriminate on runtime information.
