PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported

[HalJordan]

src/Reducer/EvalReducer.php

src/Reducer/EvalReducer.php:        if (substr($code, 0, 2) == '?>' && $code{2} != '<') {
src/Reducer/EvalReducer.php:            $code{0} = '<';
src/Reducer/EvalReducer.php:            $code{1} = '?';

Those 3 lines just need to be changed.

For reference, this is due to curly braces for string indexes being removed in PHP 8:

https://www.php.net/manual/en/language.types.string.php

Note: Prior to PHP 8.0.0, strings could also be accessed using braces, as in $str{42}, for the same purpose. This curly brace syntax was deprecated as of PHP 7.4.0 and no longer supported as of PHP 8.0.0.
