Looks good to me. cq- so you don't enable it by default.

I don't think you want to commit these.

Note, you could write a test for these if you wanted. You would just enable these dump/warn flags at the start then trigger some messages. But I'm not sure that would be too valuable.

I wonder how our jsmin.py is doing minifying with new syntax (template strings, arrow functions, etc). I wonder if the first time we have a newline in a template string if we will run into issues.

We already have some, I think.

Just timestamp()?

I think we should use this. The other places should change.
