Actually, I would never write such garrish code (normally). Allow me to explain my use case (and how I found out about this):
I have a function that converts a string into an array. For instance, the string "[0, 1, 2, 3, 4]" gets converted into the array [0, 1, 2, 3, 4].
It needs to be able to handle a variety of situations; strings, booleans, numbers, etc. So I wrote a bunch of unit tests to verify that it is working properly. They have already helped me catch a couple regressions.
The goal of the function was to convert the string as accurately as possible, so if you pass in the string "[,,,]" you should get back the array [,,,]. I had a unit test that verified that commas in the string would properly get converted to commas in the array.
When running these unit tests in JSLint, I stumbled upon the error, hence this post.
