Hi, I was trying to use this amazing project but stumbled upon the issue. Here is output that I'm getting:

panic: interface conversion: interface is nil, not reflect.Type

I'm running go version go1.8.3 linux/amd64 on Arch Linux.

Here is the smallest project that I was able to reproduce the issue in:

https://github.com/Gonzih/go-pry-panic-issue-reproduction-example

Please feel free to ask for any extra information on my setup.

Thanks a lot!

I have the same issue

I see a similar failure -- it may be more appropriate to have a separate issue:

Sorry about that guys! I added some new features to the language last night and messed up the interface{} handling.
