In these cases, the defaults are annotated as = ..., which at runtime would be _NoValue, so these annotations should therefore also accept _NoValueType.
But this is currently not the case for the following function parameters in _core/fromnumeric.pyi:

• argmin and argmax
  • keepdims
• clip
  • a_min and a_max (also missing defaults)
  • min and max
• sum and prod
  • keepdims
  • initial
  • where
• ptp
  • keepdims
• amin and amax
  • keepdims
  • initial
  • where
• std and var
  • keepdims
