Write while loop equivalent in elixir

@lucaong

the original stream is actually infinite, but it only gets realized in a finite number of elements due to Stream.take and Enum.find

I would understand that the “repeatedly” is infinite, but then my first guess would be that the second part “takes” 16 instances from the infinite stream and passes to the third part, which enumerates over them, or so. But it seems like backward thinking in the context.

@dimitarvp

One good “brain hack” is to think of Enum as “the result of this will be immediately calculated and passed to the next function” and of Stream as “this will be calculated at the first occurence of Enum down the line”.

Right - think it backwards
