In my eyes the > array case is a no-brainer, but for string access maybe not... Good question. I did consider whether it would make sense to only deprecate curly brace offset access for arrays and not strings. The problem with this is that it wouldn't solve the issue of confusion outlined in the RFC. Unless the bracket syntax for string offset access was also deprecated, users would still be left to question whether the curly brace syntax behaves differently in certain circumstances, if one alternative performs better than the other, if there is a scoping related difference, or when the curly brace syntax should be used instead of the normal bracket syntax for string offset access. > Would it be possible to compare the string access only for both > curly & straight braces and the same for array access? I updated my script to list all the unique variable names referenced in the output of Nikita's analysis of the top 2k Composer packages: https://gist.github.com/theodorejb/ba35fc8f72df8823e07c5f3b51870e00. The most frequent variable name is `$string`, and from numerous other variable names it does seem that the majority of curly brace usages are on strings (other frequent variable names include `$code`, `$Bytestring`, `$chrs`, `$text`, `$str`, `$numberstring`, and many similar examples). I also dug into the repositories for a bunch of the packages, and most of the curly braces uses appear to be in older code without any type declarations (which may explain why so many variable names include a type).
