Hi,
To me `;` means not "empty body" (that's `{}`) but really "no definition,
only declaration" (or "no body, only signature", and also "no code
executed"), i.e. an *abstract* method (either explicitly declared so in a
class, or implicitly in an interface).
Granted, property promotion is already special (cannot be used in an
abstract constructor), but it can also be mixed with non-promoted
parameters and body, so I feat that your proposed alternative syntax would
bring more confusion than convenience :s
