[Freeciv-Dev] Re: using OR in requirements

[Jason Dorje Short <jdorje@xxxxxxxxxxxx>]

Sorry, to be more verbose:

We discussed having OR before, and decided it wasn't a good idea because 
of added complexity.  If it were only done for effects and then things 
were split during ruleset loading, that might be feasible.  The problem 
is that reqs are used in lots of places and have a consistent format; 
how will you add extensions without breaking that format?
[effect_martial_law_each_0]
name    = "Martial_Law_Each"
value   = 1
one_of_req  =
    {
        { "type",       "name",      "range"
          "Gov", "Anarchy",   "Player"
        }
        { "type",       "name",      "range"
          "Gov", "Despotism", "Player"
        }
        { "type",       "name",      "range"
          "Gov", "Monarchy",  "Player"
        }
    }

this preserves the req format but in an array.  However I'm pretty sure 
this isn't possible with the registry format.
