Hi, I'm Derick. Welcome to PHP internals news, a podcast dedicated to explaining the latest developments in the PHP language. This is episode 96. Today I'm talking with Jordan, about a user defined operator overloads RFC that he's proposing. Jordan, would you please introduce yourself?

- Jordan LeDoux 1:41
-
Quite a bit more. Yeah.

So what is this RFC that we're talking about today?
