Thanks for filing this bug.  It bit me too and I was just
digging through my mail archives to figure out what was going
on...

Right, it can hide/obscure actual errors.  And it is harmful if
users are logging and run out of disk space.

Your proposal is much better than the current situation in
2.7.0dev.

However, the ideal situation is that Ruby NEVER breaks or
complains-by-default about code which worked in the past.

Again, users abandon Ruby because of having to change/update
previously working code due to incompatible changes and
deprecations with every release.  I am now more strongly
considering setting aside time to rewrite some of my old
projects in a more stable language.
