Current behavior is completely intended, so it's not a bug.

In old days, I thought that std.traits.isSomething should consider alias this
types. That was necessary for std.format and std.conv implementation. For the
purpose I added std.traits.SomethingTypeOf, and used them as the implementation
of isSomething.

https://github.com/D-Programming-Language/phobos/pull/488

But, the change of isSomething's behavior had been complained as a bug by some
peoples. They said "isDymanicArray!T should be true if and only if T is
actually a dynamic array type. If T is a struct with alias this, it should
return false".
I finally agreed with that and reverted the behavior.

https://github.com/D-Programming-Language/phobos/pull/976

Now, std.format and std.conv uses is(SomethingTypeOf!T).

Furthermore, SomethingTypeOf is now *undocumented* templates, so their
specifications are "as-is". (But considering "alias this" type is sometimes
useful, so they are not marked wit "package".)

If you really need SomethingTypeOf, please open an enhancement that they should
be *documented*.
