digitalmars.D.learn - I need to use delete as the method name. But now it's still a keyword,

My code:

```D
import std.stdio;

class HttpClient
{
	string get(string url)
	{
		return "";
	}

	string delete(string url)
	{
		return "";
	}
}

void main()
{
	auto http = new HttpClient;
	
	string content = 
http.get("https://forum.dlang.org/group/general");
	string content = 
http.delete("https://forum.dlang.org/newpost/general?");
}
```

error message
```bash
% dub build --compiler=dmd
Performing "debug" build using dmd for x86_64.
test ~master: building configuration "application"...
source/app.d(10,9): Error: no identifier for declarator `string`
source/app.d(10,9): Error: declaration expected, not `delete`
source/app.d(14,1): Error: unmatched closing brace
dmd failed with exit code 1.
```

I wonder when I can use it. Because this will cause a software 
naming problem.

Considering the deprecation period has ended then IMO it should 
be able to be used as an identifier.

I would consider this a bug.

No, it's intentional.

https://dlang.org/changelog/2.100.0.html#deprecation_delete


 Starting with this release, using the delete *keyword* will result in 


a *compiler error*.

It's still a keyword according to that. I'm assuming a future release 
will remove the error, and then you can use it as a symbol.

The body is now available, and hopefully the delete keyword will 
be deprecated soon.

To be honest, it's not clear that it's intentional from the 
description of the changelog. It just says using the keyword will 
result in an error, not using the keyword as an identifier, which 
isn't the same at all.
