Question: Using fsolve for solving a set of equations involving procedures

(1) Maybe the following problem is closely related to "An easily corrected limitation to symbolic derivatives in fsolve() when solving a system of equations" in TomM's blog.

(2) The problem: I would like to solve a set of equations with

     fsolve({f(x,y)=0,g(x,y)=0},{x,y},{x=-10..10,y=-10..10};

      with the procedures

     f:=proc(x,y) x^3-sin(y); end proc:

     g:=proc(x,y) 

          local sol:

          sol:=fsolve(q^5+x*q^2+y*q=0,q,complex):

          Re(sol[1]+1);

     end proc:

    With the modifications suggested by TomM in 'fsolve/sysnewton' it doesn't work. The Maple error message is:

   Error, (in fsolve) {x,y} are in the equation, and are not solved for

   I think the problem is the  "complicated"  procedure g, which itself  contains  fsolve.

Could anyone help? I think this problem in solving sets of equations involving procedures  is rather general .

Thanks,
