Foreach-loop with break/return vs. while-loop with explicit invariant and post-condition
This is easy.
Almost nothing matters more than clarity to the reader. The first variant I found incredibly simple and clear.
The second 'improved' version, I had to read several times and make sure ...

Foreach-loop with break/return vs. while-loop with explicit invariant and post-condition

Foreach-loop with break/return vs. while-loop with explicit invariant and post-condition
