Dik, I like this addition, but I think the name “repr” might be confusing to PHP developers who aren’t familiar with Python idioms. PHP function names and coding standards within the community tend to lean more toward verbosity than terseness, when it comes to naming things. Perhaps we should follow the lead of __toString() and use __toRepresentation()? Maybe also introduce a Representable interface, like Stringable? https://wiki.php.net/rfc/stringable Cheers, Ben
