This assert is redundant with the one in zend_enum_obj_from_obj(). I also don't see how it could help with codegen.

The _decl files should be listed in .gitattributes as linguist-generated -diff.

The leading underscore is not necessary and I believe for newer symbols we already don't have it:

| zend_long case_id; | |
| int case_id; |
I believe enums are int (unless a type is specified, which is only possible as of C23). Also applies to zend_enum_next_case_id() and similar.

Update
gen_stubs.phpto generate C enums from internal enums. Enum values can be compared to the result ofzend_enum_fetch_case_id(zend_object*).The generated enums are added to separate files named
{$extensionName}_decl.h(one for each extension declaring some enums), so that it's possible to include these from anywhere._arginfo.hfiles would generate warnings if we tried to include them in a compilation unit that doesn't call theregister_{$class}functions, for instance.Introduce
