Body macro can’t be attached to variables

[ahoppen]

The function body macro proposal states:

When using the shorthand syntax for get-only properties, a function body macro can be applied to the property itself:

But the following does not compile

@stringify // error: 'body' macro cannot be attached to var ('x')
var x: Int { 2 }

With stringify being a function body macro.

Attaching a function body macro to a getter also doesn’t work:

var x: Int {
  @stringify get { 1 } // error: Declaration is not a type with an optional code block
}
