Feature Request: automatically print expression on variable assignment (similar to pry)

[jdsutherland]

pry (ruby REPL) has a feature where the resulting expression is printed during a variable assignment.

Here's a screengrab for clarity:

I find this useful as I'd often like to see each result when sending existing code (containing variable assignments) to ptpython from vim. Currently, it seems that one has to retype the assigned variable to view results, which is a bit slow.

Is this an existing feature? If not, might you consider a PR? I imagine it'd be preferred as an optionally configurable feature.

Interesting idea!

Unfortunately, right now, I won't have time for this. First finishing prompt_toolkit 2.0 and making sure everything (including ptptyhon) runs on 2.0. Then we can start again on new features.
