Good to know. Yet, I wonder why such changes are not discussed on this
NG and at the very
least announced in the change log...
On topic: this means a pure function can take a reference to data that
can be mutated by
someone else. So we're giving up on the "can parallelize with no
dataraces" guarantee on
pure functions?
A const pointer to unshared data cannot be modified while inside a pure
function. The key is that it's unshared.
What it does disable is caching based on the reference value.
