[New-bugs-announce] [issue40890] Dict views should be introspectable

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

Dict views wrap an underlying mapping but don't expose that mapping as an attribute.

Traditionally, we do expose wrapped objects:  property() exposes fget,  partial() exposes func, bound methods expose __func__, ChainMap() exposes maps, etc.

Exposing this attribute would help with introspection, making it possible to write efficient functions that operate on dict views.
