Will the alternative syntax on hook not even be put to a vote?
I think the "prefix-style" syntax breaks the standard property signature template that
exists since PHP 5!
Natural syntax:
<visibility> <types> $<name>;
With prefix-style:
<visibility> <visibility>(set) <types> $<name>;
This introduces a syntax that is totally unexpected to natural reading. In my opinion, pretty ugly.
What about some static code analysis tools? What about using regex to parse code and syntax in PHP
(which takes a lot of work to build) for extensions used in IDEs like VSCode, IntelliJ, etc.?
To parse Property Hooks, a lot of time and work will already be spent adapting to the new syntax,
and now this as well? Why not take advantage of the new Property Hooks syntax newly implemented?
Implementing visibility in the hook, which can be now the default API of the properties, would
further enhance the syntax of Property Hooks, which in my opinion is one of the best features of PHP
in the past five years.
If more operations on Hooks are implemented in the future, what is the use of this syntax? How could
it be used? For example, an operation that is called only when a property is first set:
init hook.
public $prop {
private init => //...set a default initial value here
}
A hook called 'push' only for arrays, would solve some semantic problems and make it clear
to separate the set operation (set values of an array) vs push only one item to the array as I
showed in the example above.
What about other operations that are already common when we use magical methods in the future:
unset, isset, etc.?
In the Property Hooks RFC, it was mentioned that more hooks may be added in the future.
It may be a default behavior for developers to want to override all magic methods for properties
using Property Hooks. For now there is only get and set, but what about unset, isset, etc? How is it
to define the visibility for this in the future?
public private(set, unset)....
??
Where would new operations beyond the set will enter this syntax?
Cheers,
