Typed-functions breaks mathjs for iOS 9.3

https://github.com/josdejong/typed-function/blob/master/typed-function.js#L1096
This throws TypeError: Attempting to change value of a readonly property. thus preventing mathjs to load.
Tested with iOS 9.3 (can be reproduced with desktop safari 9.1).

I think the 'name' property of a function is configurable (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/name) and so we can delete it first and then reassign it a value to work around this.

I don't think this will work on older browsers though. Is the name of a function used apart from as a debugging tool? If not then this entire line could be surrounded by a try-catch so that typed-function can still work when this breaks.

I don't think this will work on older browsers though.

I confirm, just tested that on safari 9.1 :

Thanks for reporting this issue!

It should be easy to make a fallback for older browsers and browser that don't allow replacing a function name, will look into it within a few days.

I am also seeing this on older android versions. Threw me for a loop cause didn't have a clue where the error was coming and it's just including the mathjs@4.0.0 release.

This should be fixed now in v4.0.1
