This whole argument is silly (the semicolon in JS argument, not this post itself). JavaScript was built for semicolon use, use them. If you don't want to use semicolons then at least make sure you aren't breaking major libraries that are in mass use. If it does break something many people use then work with the creator to fix it. If he refuses to fix it then ignore everyone using these libraries, provide a weird workaround, or just use a semicolon! Personally I've created a branch off of bootstrap and another library (can't remember off top of my head) that adds in semicolons as to not break JSMin which is critical to my deployments of websites.

Jsmin is broken if it can't handle missing semicolons.

Googles closure tools actually do parse the Javascript and can properly minify them better.
