// The pattern shown here IS NOT RECOMMENDED.

In Chromium 30 (which is the version of the Android 4.2.2 WebView) Function.name is not spec complaint, and vuex-typescript relies on it being so. More specifically (function () { var x = function () { }; return x.name; })() should return "x", but in Chromium 30 returns "" since it is an anonymous function. For this situation I found using classes with the Hander decorator is absolutely necessary.

Since Function.name is an es2015 feature https://www.ecma-international.org/ecma-262/6.0/#sec-setfunctionname, and some vuex-typescript users will be targeting mobiles, it would be helpful documenting this use case; perhaps in the readme.
