Hi! I was trying Lazy and the primes example doesn't work:

julia> using Lazy

julia> import Lazy: take, range

julia> isprime(n) = @>> primes begin
           take_while(x -> x <= sqrt(n))
           map(x -> n % x == 0)
           any; !
       end
isprime (generic function with 1 method)

julia> primes = filter(isprime, range(2))
Error showing value of type Lazy.LazyList:

julia> Pkg.status("Lazy")
 - Lazy                          0.10.1

I found no reference to take_while in the repo, other than inside this test.
