TypeError: Bignumber is not a constructor with webpack

When bundling with webpack, I keep getting this error:

TypeError: Bignumber is not a constructor

Likely related to how default exports are handled in the dependency:
dignifiedquire/borc#41

Any possible workarounds?

I think dignifiedquire/borc#41 is where you're going to find someone who's figured out a workaround unfortunately.

This issue is likely be fixed. Please re-open if it is still there.
