class_docstr: A class that specifies the rewrites/optimizations used during function compilation.
  
  Parameters
  ----------
  optimizer
      An Optimizer may simplify the math, put similar computations together,
      improve numerical stability and various other improvements.
  linker
      A Linker decides which implementations to use (C or Python, for example)
      and how to string them together to perform the computation.
  db
      The `RewriteDatabase` used by this `Mode`.  Note: This value
      is *not* part of a `Mode` instance's pickled state.
