Eager head evaluation in Stream

[Paweł Krupiński]

Hi.

I was wondering what was the reason for the eager evaluation of the head of the stream?

For example if I map a Stream, the function will be applied to the head eagerly and to the tail lazily.

This is quite inconsistent, confusing and occasionally leads to strange bugs (for example when processing things in batches or interacting with lazy lists created by Hibernate).

Does anyone know?
