[rules-users] using Globals in LHS (not using eval)

[Wolfgang Laun]

Given that you have
   global Integer foo;
you can write
   when
      Person( age > foo )
without eval. But you have to be very careful: Don't expect changes of
foo to work like update for facts, and make sure to set the global
before you insert any facts where patterns for that fact refer to the
global.

You cannot use a global's type the way you use a fact type as a pattern.
