lib-main-dev.js is an example of the output when running 'webpack -d', which is short for '--devtool sourcemap --debug --output-pathinfo', it has the same problem*
There are really two problems contributing to this.
First, webpack rewrites import/export statments and never introduces a variable binding with the same name as the bindings used in the original import/export.
Second sourcemaps _do_ map lines of compiled code to lines of original source, but they _do not_ map renamed variables to original names. As an example, enable minifiaction and soucemaps then try to debug a function. You might notice that the variables are all called a, b, c, and other short uglified strings now.
* I just realized that the file I uploaded is missing the ends of each line, so that file is incorrect.
