Description
The current mutation API is inflexible: it only supports a few operators, which can flip (but why not replacing + by *, not only by -).
It is also inconsistent: deleting a line is modeled as an operator with a flip method.
We should improve the mutation API to support more mutation rules on more AST nodes.
