You implemented *some* of it.

The part I specifically wanted wasn't released until September 
2018

https://dlang.org/changelog/2.082.0.html#uda-function-parameters


I don't recall when the basic UDAs were added and I can't find it 
searching the changelog right now, but if memory serves, it was 
about 2013 (which is late enough that I already had other 
alternatives to them implemented in my web server library), but 
there was a gap of *several years* between your initial 
implementation and it actually covering all the bases to make it 
compelling.


This is a good example of the overall point: so many things are 
announced with much fanfare as soon as they do the bare minimum 
of functionality....... then it sits at bare minimum for an 
unspecified amount of time before it reaches the point where it 
is actually useful, if it ever reaches that point.
