C# and Java both have attributes, following these established design

At the Lang.NEXT conference over the last 3 days, I was able to talk to
many smart people about attributes. But I did find some confusion - are
they best attached to the variable/function (i.e. "storage class"), or
attached to the type ("type constructor")? I think the former.
Attaching
it to the type leads to all sorts of semantic issues.
From your list of uses, it looks like attaching it to the variable or
function is an apropos solution.
They should be attached to declarations.
The question was whether the declaration affects the type of the
declared or not.
For user-defined attributes, no. This is metadata for the programmer/lib
to decode.
Obviously, compiler-defined attributes can.
