Subject: Re: [DISCUSSION] Match expression
From: tovilo.ilija@gmail.com (Ilija Tovilo)
Hi internals
Just a heads up, I'd like to start the voting on the match expression
RFC in a couple of days.
https://wiki.php.net/rfc/match_expression
I have made a number of changes to the RFC.
* Block return values are now allowed but limited to match arms
(https://wiki.php.net/rfc/match_expression#blocks)
* Nikita and I have discussed this here:
https://github.com/php/php-src/pull/5407
* continue targeting match is no longer allowed (compilation error)
(https://wiki.php.net/rfc/match_expression#breakcontinue)
* Minor rewording
The jury is still out on:
* Optional semicolon when using match as a statement
(https://wiki.php.net/rfc/match_expression#semicolon)
* It makes the grammar somewhat complicated
* Nesting match expression blocks without parentheses aren't
possible (https://github.com/php/php-src/pull/5407#issuecomment-616612763)
* Compilation error when not returning a value from a block
(https://wiki.php.net/rfc/match_expression#blocks)
* When the block terminates (e.g. through throw or exit) no
return value is needed but the current implementation requires it
* We could make this a runtime error instead
If you have anything new to add to the discussion, this is your chance!
