Hi Juliette,=0A=
=0A=
I just analyzed the top 1500 Composer packages for a couple more of the pro=
posed syntax=0A=
deprecations, and found the following:=0A=
=0A=
## Deprecate non-standard cast names:=0A=
197 non-standard casts in 25 unique packages.=0A=
=0A=
## Deprecate backticks as an alias for shell_exec:=0A=
49 backtick operator executions in 10 unique packages.=0A=
=0A=
I find it ironic that the more widely used of these proposals has the least=
 opposition to=0A=
deprecate (100% in favor so far), while deprecating semicolon-terminated ca=
se statements=0A=
(which has zero usages in the top 1500 packages) currently has more opposit=
ion than either=0A=
of these.=0A=

Perhaps the deprecation seems unnecessary at first, but there is a non-zero=
 cost to=0A=
maintaining this legacy alternate syntax in the language:=0A=
=0A=
1. It requires projects and coding style guides to choose and document whic=
h syntax to use.=0A=
2. Coding style fixers like PHP-CS-Fixer and PHPCS have to implement and ma=
intain fixers=0A=
to enforce one of the syntaxes.=0A=
3. Who knows whether the alternate syntax may block future proposals, as wa=
s the case for=0A=
the curly brace array/string offset syntax, which being deprecated in PHP 7=
.4 made it=0A=
possible to implement property hooks in PHP 8.4.=0A=
=0A=
Kind regards,=0A=
