[bioinfornatics]

I write a function with Lambda expression + safe + pure wich do 
same (close) as countUntil

but i fail to use lambda expression into my function. I try by 
two way
- alias this pred … (to get a default lambda)
- function(…) pred

both way i fail, could you take a look to code please.

Goal is to get a pure and safe function

thanks
