Description

Feature Request

Better support when displaying visualizations for debugging, especially for unordered maps, maps, and arrays.

For example, on a physical mac machine compiling with clang++ and using LLDB, this is the current experience:

We should make it easier to see the array size and elements, as well as the items in each unordered map.

There is also limited support for mutexes, with no indicator whether a mutex is locked (in this case, the mutex was named locked):

Research direction

Start by reproducing the visualizations on a physical Mac with clang++ and LLDB, then trace the existing support for arrays, maps, unordered maps, and mutexes. Done means array sizes and elements, map items, and a mutex's locked state are displayed more clearly.
