I would like to point out that the documentation for 
property-functions needs improvement: 
https://dlang.org/spec/function.html#property-functions

Cool, this feature is what i just needed -> me, happy
Then i see the warning -> mental pain

This is a very unpleasant situation. Should i use it? Should i 
not? How long is the Warning there already, is it still valid? - 
a review is mentioned but no link to the process is given. This 
telling me basically: There are property-functions, but there are 
$kind_of_broken, you can use it - but maybe it will be removed 
tomorrow.. or next year, or never. :)

TL;DR
The Documentation raises more questions than it answers.
What is the state of property-functions?

It works ok for basic cases. Broken cases include:

foo.prop += 5 // you must do foo = foo + 5

foo.callable_prop(); // if it returns a callable, you prolly have 
to use double parens to actually call it, foo.callable_prop()()

&foo.prop // gives a delegate, unless it returned ref



Otherwise it really isn't too bad just you don't need the 
 property annotation itself, all it actually affects is 
typeof(foo.prop) and like override mangling.

So if you never used  property you probably wouldn't care too 
much.

If you do use it, be aware of the three potential gotchas above 
and be advised if you do some kind of hack to work around this, 
you thing might break some time around the year 2245 at the 
current rate of progress. Maybe the crew of the starship 
Enterprise will have their code break when  property's 
"definition is more certain and implementation more mature" but 
you probably shouldn't worry too much about it.

Property functions are currently in a limbo state right now, as 
the implementation is unfinished. The D language leaders has not 
comment on the state of  properties for years already, as it 
deemed to be not of top priority. The current state of it is 
considered to be obsolete, by other programmers here.

You can track my progress of finishing the implementation of it 
here: https://github.com/dlang/dmd/pull/12097

Currently it is on hiatus as the debugging information provided 
by dmd is god awful. I am currently working on improving the 
debugging experience for visual studio, by focusing on the debug 
info that is generate by dmd.

What is the current status, is the D project going to pursue 
 properties and do a full review how it can be implemented or is 
this feature going to be deprecated?

Neither. They deemed it not important right now.
