If you'd like an example of replacing ES classes that use the `export` keyword,
check out the [babel example
project](../examples/babel/test/lib/calculator-test.js). (Note that the test
itself must fall back to CommonJS-style `require` statements, since module
replacement requires the dependency be loaded after the replacements are
configured, which precludes the use of the static `import` statement.)
