Comment(by novoselt):
Ah, now that makes sense! I guess I just have an issue with `_is_zero`
because I looked at the source code of it for some polyhedron (which
happened to be exact) using `??` and saw `x == 0` without paying too much
attention to the details. The `Polyhedron` class itself does not have such
a method at all. Is really speed-crucial to set it to a lambda-expression
instead of having an honest method with if-check for the type of the field
each time? (For the purposes of this ticket 2 is resolved.)
