What stupid mistake? It was an NPM bug.

[divs1210]

Yes, but the package on npm is, indeed, corrupt and the latest semantic version.

Anyone creating a fresh project right now with uglifyjs somewhere down the build chain will face this issue.

The only way to resolve this is by publishing a fresh, correct version to npm ragardless of what caused the issue.

The authors have failed to do this till now and the issue remains closed.
