alias myInt = int;
but the specification says nothing about such use alias. Is the 
syntax has been changed?

Sorry, I wrong :
AliasDeclaration:
     ....
     alias AliasInitializerList

AliasInitializer:
     Identifier = Type

It seems that it's documented here, albeit not clearly:
http://dlang.org/declaration.html#AliasInitializer

I don't see any mention of it here:
http://dlang.org/declaration.html#alias

I recall there being some issues with alias this = identifier, 
not sure if that's been resolved. Regardless, I think the 
documentation at the latter link needs to be updated.

Yes, it's a recent very small syntax improvement. Eventually I 
hope the older syntax will be deprecated. The old syntax is still 
used for the "static this" in structs.

DScanner now issues a warning when run with the --styleCheck or 
--syntaxCheck options suggesting that the user switch from "alias 
a b" to "alias b = a".

It also warns on implicit string concatenation, which has saved 
me a lot of debugging in situations like this:

enum someStrings = ["abc", "def" "ghi", "jkl"];

This should be an error in the language. Please add your 
experience (and vote, if you want) to this thread:

A note about your experience is probably more important than the 
vote.

You can add some bugs you have had to debug, some comment about 
the frequency of this problem, etc.

You meant "alias this".
