Add setting for switching between "production" and "interactive" mode
It seems that future development in Pandas creates a distinction between "production" and "interactive" use. I frequently use Pandas to do interactive data analyses. As such, things like indexing shortcuts are very handy. However, I also can see that some of this magic can create very subtle bugs in production systems.

One potential solution is to have a global configuration switch. When an analysis project starts, many of these "shortcut" functions could be made available. Once the code is ready, the user can change this setting to "production" which would issue warnings for functions deemed unsafe.

Any thoughts on this?

This issue came up while talking to @jreback on #13548 .
