Here a bigint implementation proposal.
https://github.com/jfcap/janet.git (branch bigint)
It's not finished.
But at this stage, some feedbacks are welcome.
janet:0:> (def a (bigint/uint64 0xfff))
4095
janet:30:> (def b (bigint/uint64 "0xffffffffffffffff"))
18446744073709551615
janet:75:> (:/ b a a)
1100048695360
janet:86:> (:- b (:* a 2))
18446744073709543425
janet:102:> (type a)
:core/uint64
TODO :
* marshal/unmarshal
* more operators (bitwize operations ...)
* ... ?
* adding typedArray (u)int64 back ;-)
some tests are available in suite6.janet

I removed them because there is no way to manipulate them, and likely never will be via the standard number type (a C double). If you read the JavaScript standards for typed arrays, they don't include 64 bit integer support at all for this same reason. I was alerted to the problem via warnings in the Microsoft compiler on Appveyor.
Considering how easy it is to add them back, we can add them if we ever support proper 64 bit integers, maybe via some boxed representation (core/bigint?)
