My apologies for seeming sarcastic. I understand why. I also know it's not intended as sarcasm. Text is hard and it's hard to balance the line of making points. I think it is wonderful when Delphi adds features, quite genuinely, and the post said so. I edited to try to help that understanding, but the original said "congratulations", and that is sincere, and I retained that comment.
It's hard reading that kind of reply, Daniel, and I don't know what to make of it. I think the best thing is to apologise because it's clear you are offended: and I am sorry for that.
Let me pontificate a bit: I worry about language compatibility. There are multiple Pascals out there: Free Pascal, DWScript, etc etc. Yet Pascal is a small language. If Delphi ever added any other feature Oxygene or Free Pascal or anyone else already has, and chose to do so with different, incompatible syntax, that would be a significant statement. I use Python a lot, it gives me the same "feeling" as Delphi when I use it, I have talked about Python a lot to people with quite some enthusiasm, it has a ternary if, and that ternary if is inverted -- that structure is legit, and Delphi could have used it, and then imagine if we had two versions in Pascal! Far better to copy, when it's already been done -- with code existing for years, it's key to keep the same syntax compatible. Equally, there's so much the language could do. When it moves forward, I hope it does so in ways that copy the path that has been led by others. Perhaps that is the message in the blog post: keep going; there's more, follow. I would certainly prefer it's read that way. Please read again, I hope it's gentler.
For this forum... that was not the message. I had intended to directly answer a thread about a language feature with a blog post showing a snippet of the language feature the OP asked for. Message: it is possible, look! I fully respect you don't want other implementations mentioned, and will respect that.
