#255

It might seems like a lot of changs, but actually it is mostly an additional .into() for each const point_id used in tests

Is this an unrelated issue existing in the main branch?

[generall]

no, it's due to the change, that we can not calculate the next ID anymore

[agourlay]

All those into() are rather noisy but I do not see a better alternative.

same, there are no implicit conversion like in Scala. But it is only noisy in tests
