Thanks, I forgot that issue.

But we now have %{ and %r{ , so why not add a third case for example %c{ which
behave in the same way except that it do not throws a warning and that it do not alter
the return value of a method/block?

I think that way, we don't have to make so many changes to the Ruby interpreter.
