Detailed Description

Implements dwim-print, a printing command that chooses the most direct, efficient, and resilient means of printing a given expression.

DWIM is an acronym for Do What I Mean. From Wikipedia, DWIM is described as:

‍attempt to anticipate what users intend to do, correcting trivial errors automatically rather than blindly executing users' explicit but potentially incorrect input

The dwim-print command serves as a single print command for users who don't yet know, or perfer not to know, the various lldb commands that can be used to print, and when to use them.
