Typed List causes IPython console to hang when gets printed

See original GitHub issue

Reporting a bug

I have tried using the latest released version of Numba (most recent is visible in the change log (https://github.com/numba/numba/blob/master/CHANGE_LOG).
I have included below a minimal working reproducer (if you are unsure how to write one see http://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports).

All elements of numba’s typed List get printed to IPython console, causing it to crash if the list is long. This doesn’t happen with Python’s native lists, as they get shortened when printed.

In [1]: x = [1] * 1_000_000
In [2]: y = numba.typed.List(x)
In [3]: y

@ma-sadeghi thanks for confirming, I think you are just experiencing the effect of buffering a large amount of output. I think this should be reasonable to fix, just by restricting the amount of printing done for the List type.

@stuartarchibald @caljrobe @esc I was a bit swamped, so couldn’t get back to this issue promptly, sorry about that. I just opened up a PR that addresses this issue.
