Current declaration grammar contains both D style syntax and C style one.
Decl:
StorageClasses_opt BasicType Declarators ;
[snip]
Declarator:
BasicType2_opt ( Declarator ) DeclaratorSuffixes_opt
BasicType2_opt Identifier DeclaratorSuffixes_opt // [x]
[snip]
DeclaratorSuffix:
[ ]
[ AssignExpression ]
[ Type ]
Parameters MemberFunctionAttributes_opt
TemplateParameters Parameters MemberFunctionAttributes_opt Constraint_opt
The grammar [x] accept both:
int[] var
and
int var[]
But it's confusing, and hard to understand what the grammar will accept. Instead of mixing C style grammar rules under the one "Declarator", I'd propose to separate them into "AltDeclarator".
And finally we can easily say that the AltDeclarator will be deprecated.
