proj4 require statement errors with parcel bundler

[JoeGermuska]

When trying to use reproject in a project built with Parcel v2, the build errors when scope hoisting with this:

🚨 Build failed.
@parcel/core: node_modules/proj4/lib/index.js does not export 'hasOwnProperty'
/Users/germuska/Development/censusreporter/node_modules/reproject/index.js:3:13
  2 | 
> 3 | var proj4 = require('proj4').hasOwnProperty('default') ? require('proj4').default : require('proj4');
>   |             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  4 | // Checks if `list` looks like a `[x, y]`.
  5 | function isXY(list) {

With Parcel v2, turning off scope hoisting prevented the error, but of course, at the expense of the optimization benefits that enables.

I was able to work around this by copying reproject/index.js into my own codebase and replacing line 3 with
import proj4 from "proj4"
