Think I found a bug in babel-minify: @mavoweb's minified version has a bug that the normal version doesn't. Try changing the dependency to non-minified Mavo here: codepen.io/leaverou/pen/Qrdg… How does one create a reduced testcase for a minifier?! I don't even know where to start. 😕

Reducing the @mavoweb side to something more minimal (if that's useful, not sure if it is) should be similar to reducing for a browser bug. Just like it's useful when reducing for a browser bug to check after each step of reduction that it still shows the bug in the bad... 1/2

...browser and works in the good browser, it's likely good to check after each step of this reduction that the minified version still has the bug and the unminified version still works correctly. (It's useful because you might otherwise end up with code broken both ways.) 2/2
