Dear list

I was pleased to find out that the following in erlang just works fine

Eshell V5.8.3  (abort with ^G)
1> 1 bsl 70.

I'm then evaluating to use bitwise operations on bignums (up to 128
bits) and I'm asking if anyone can share how internally bignums are
represented what's the overhead of using them and if there are any
caveats related to their usage.
