Which is highly nonsensical and basically shows that alias this should have been done as a (or more than one) specially named member instead, as the syntactic pun appears not to be working.

Pretty sure "alias this" was actually a driving force. E.g

"You should use alias this?"

"How, I added alias this and it didn't compile?"

"The syntax 'alias TheThingToAlias this'"

"So not 'alias this' then."

It was actually removed several releases ago -https://github.com/D-Programming-Language/dmd/pull/1413

The syntax was actively removed.

New slogan: D'precated

I hope not. :p

Because more syntax is always better !

What a mess!  I'm almost sorry I brought it up, but I'm glad I did because I was just about to model a 1500 page ARM Cortex-M datasheet using the apparently "old" syntax.

So let me get this straight:
alias {type} this;               // only if using 'this'
alias {newType} = {existingType} // all others

So, does the language reference here (http://dlang.org/declaration.html#alias) need updating?

And do the aliases in object.di here (https://github.com/D-Programming-Language/druntime/blob/master/src/object.di) also need updating?

Yeah, I actually just right clicked the word for the correction and the i didn't register for whatever reason. Fwiw, I said the word correctly in my head

Now we're just being mean. :p

D works great for me (it's just sometimes some of these discussions like this get me concerned over mostly trivial things).

Yes, but:

1) not {newType} but {newSymbol} - alias does not create new types
2) alias {existingSymbol} {newSymbol} is also legal and not planned for deprecation so far

> So, does the language reference here (http://dlang.org/declaration.html#alias) need updating?

Yes, looks like those don't mention new syntax.

> And do the aliases in object.di here (https://github.com/D-Programming-Language/druntime/blob/master/src/object.di) also need updating?

Not necessarily, old syntax is still legal. But in context of consistent style - yes, makes sense.
