isFunction(), final…

The other day I realised I actually have not presented the proper shape of the final version of my isFunction() function.

I stumbled upon yepnope.js project and started nosily browsing through the code on Github. If course I smugly noticed that isFunction() in there is “no good”, just to quickly realise I have never published the proper implementation of its final and probably the best version. Here it is then:

Update 13.Aug.11

Since Gareth insisteth (see the comments bellow), I can do nothing but oblige. Here is one much more robust version, which will work correctly, even in presence of most JavaScript comedians.

Enjoy. Even better: use.
