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

My code:

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

% dub build --compiler=dmd
Performing "debug" build using dmd for x86_64.

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.

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.
