This is **not** true. Both @@ and #[  will break existing PHP 7 code!

The question is how likely each of them is. #[ will be slightly higher than
@@ - but both will still be in the 0,000001% range of occurrences.

and for *both* the same Fix is a project wide sed that replaces @@ with
@<space>@ and #[ with #<space>[ respectively.
