Doc #72500 [NEW]: Imprecision about compatibility of "Variable variables and global"

From: gwenael dot chailleu at gmail dot com Operating system: PHP version: 7.0.8 Package: Documentation problem Bug Type: Documentation Problem Bug description:Imprecision about compatibility of "Variable variables and global" Description: ------------ Hello, I can read in http://php.net/manual/fr/migration70.incompatible.php that "Variable variables can no longer be used with the global keyword. ". In my interpretation of this warning "global $$var;" is no longer a valid syntax and must be replaced by "global ${$var};" . But, obviously, "global $$var;" it still accepted (only tested in php 7.0.4). Is this particular syntax planned to be removed ? The code example given (global $$foo->bar;) should rather illustrate the new left-to right evaluation order of the expressions including variable variables syntax.
