Do you have an example of a new kind of attack this would allow? The proposal doesn't enable interpolation of strings coming from a database or user input - it only applies to string literals directly in PHP code. Personally I'm really looking forward to having this functionality. Just a couple days ago I wanted to call a function in an interpolated string, and it was really annoying to have to wrap the function in a closure in order to use it. If this RFC is accepted I'd be able to replace code like this: $name = "Theodore Brown"; $strlen = fn(string $string): int => strlen($string); echo "{$name} has a length of {$strlen($name)}."; with $name = "Theodore Brown"; echo "{$name} has a length of {$:strlen($name)}."; Sincerely, Theodore
