Attributes in D have two problems:
1. There are too many of them and declarations are getting too
verbose
2. New attributes use @ and the old ones do not.
I've created a DIP to address these issues.
Language defined attribs should be without @ and user defined
attribs with @
It's already not the case with @safe, @trusted, @system and
@nogc. They are not UDAs, they are defined in the language but
they start with @.
Whats wrong with it?
- some attributes are also storage classes or type constructors
(like const).
- It looks strange when you learn.
- It's confusing.
- It's inconsistent in editors (lexing doesn't tells you what
const is)
If new attributes are added they'll always be @something because
there's already too much keywords in D.
The first item in the list is interesting because people at the
beginning often think that
const int foo(){}
returns a const(int), which is not the case. Here `const` is a
function attribute, not a type constructor.
The most insane case:
const(int) foo(const int a) const
{
return 0;
}
Here it should be clear that const as a function attribute should
be replaced by @const.
