Undefined map psi in brnoeth.lib

[Jean-Pierre Flori]

Dear all,

Despite the fact that efforts are made to definie psi at:
https://github.com/Singular/Sources/blob/spielwiese/Singular/LIB/brnoeth.lib#L137
    map psi=BR,x,@a; minpoly=number(psi(A)); if(!defined(psi)){ map psi=BR,x,@a; }
    poly f=psi(B);
it seems it disappears somehow:
> LIB "brnoeth.lib";
...`
> ring s = 2,(x,y),lp;
> ideal I = x4+x,y4+y;
> list L = closed_points(I);
// ** redefining L (list L = closed_points(I);)
   ? `psi` is not defined
   ? error occurred in or before brnoeth.lib::pd2 line 138: `    poly f=psi(B);`
   ? expected poly-expression. type 'help poly;'
   ? leaving brnoeth.lib::pd2
   skipping text from `;` error at token `)`
   ? leaving brnoeth.lib::closed_points


Playing a little bit, it seems one maybe should call setring to go back into BR to make psi reappear.

Sorry for the noise.
For some reason my .lib files were not up to date...
