Can functions be procedural rather than mathematic?  If so can someone show
me how it might be done

i.e rather than..

#declare foo2 = function(x, y, z) { x + y * z }

can I do something like this, where the function returns a variables
value....

#declare foo2 = function(x, y, z)
    {
    #declare r = 0;
    #if(x>10)
        #declare r = 0.5;
    #end
    #if(y>10)
        #declare r = r + 0.5;
    #end

    return r
     }
