Which is an inconvenience for people not prepared to deal with the
issue.
It seems like it ought to be possible to warn about where and when
presumed non-aliasing is being used for optimizing purposes.  With such
a warning and observed differences between optimized and non-optimized
code, it would at least be possible for people to focus their efforts
on understanding those optimized parts of the code.
