Lazy evaluation during debug

[benmatwil]

Would it be possible to have lazy/on demand loading of variables during a debug session similar to the option in pycharm.
For large dataframes, the eager loading of its repr means that stepping through code line by line can be slow when debugging and you receive the warning each time about the slow repr on each line. By only loading the variables on demand, I assume this could alleviate this issue.

To clarify, this would be a kind of flag (e.g. in launch.json) that would make it so that no variable shows its value by default, and you have to click or expand something to cause eval? Or are you thinking of something more fine-grained?
