Hi, Some amendment have been added after this email. We are using the `=` char instead of `:`
``` $point = [=$x, =$y]; ``` And we are supporting array() and list() for this RFC now, so not only []. See the RFC for reasons. Discussions have happened in the official phpc's discord server and thanks Tim Düsterhus for the ideas. This RFC is still in a very early stage. So there can be vagueness and obvious issues. If there is, please point out. Thanks, Weilin Du
