Error handling

[go-dockly]

Hey Guys,
I saw that there are 227 uses of panic in 87 files and I do understand your motivation behind it.
Go's implicit error returns stand in the way of function chaining youd like to achieve
eg gx := r.x1.Value().(*mat.Dense).MulT(gy)
Let's assume MulT can panic inside the backward scope but that panic should recover in eg the graph wrapper scope
This should explain bit better what I mean
What are your thoughts on this?

I actually think there's a lot of room for improvement on that front! However, I wonder how to recover an error in case of a size mismatch, for example.

If I understand you correctly, you want to recover the panics generated inside the auto-grad functions (and in turn by mathematical functions) at the ag.Graph level.

Would you like to try to write some pseudo-code below for the solution you have in mind?
