SyntaxError: Deleting local variable in strict mode

[thom4parisot]

Hello,

I have tried unassertify with tinyify but I stumble on the following error with this command:

browserify -p tinyify -o static/bundle.js static/assets/js/main.js

/Users/oncletom/workspace/emunova/emunova.net/node_modules/unassertify/node_modules/acorn/dist/acorn.js:2651
  throw err
  ^

I don't use assert in my code directly so I'm unsure why this exception is thrown.

@oncletom Thank you for reporting!
It's a bit difficult to reproduce it by myself so would you create a small reproduction case repository?
