Further, minifiers have various options and some methods are more
aggressive than others.  Last I checked a couple years ago, for example,
Closure Compiler broke GNU ease.js on its more aggressive setting.  The
break was obvious from running my test suite, but some breaks were
subtle and would have caused nightmares in production.  Perhaps things
have since improved.

My point is, though, that Jelle's concerns are shared.  Closure Compiler
is written by Google, and they tend to know what they're doing in this
area. ;)

I'm not saying I'm opposed; it sounds fine to me.  Just be careful!
