The recursive error seems to be the wrong issue. Trying to
diagnose what the problem is now.
This must be some weird issue with Array or a change in what
imports does.
e.g.,
if I do
struct apple(T) { }
template Array(T) { alias apple!T Array; }
Then the code works(except I no longer can use array as an
array but I do not get any recursive issues.
The compiler I was using when it worked might have been pre
2.064... Or possibly something else is going on that breaks the
code.
Best I can tell is that the compiler is getting confused
between std.container.Array and my Array.
This seems to be a regression as it works fine in 2.064. The
error is not directly due to recursion as far as I can tell but
in a template that uses the Array template. Why it breaks the
array I have no idea. I will try to create a minimal project for
it.

recursive definition error
After upgrading to latest dmd, I get the follow error on the code
template Array(T) { alias Array = std.container.Array!T; }
Error: Array!(iDataBlock).Array recursive alias declaration
I don't see anything recursive about it... and the code worked
before. Any ideas?

Try to use a different name inside the template, like Vector.

Huh?
The template is simply wrapping std.container.Array so I can
later on use change it to a different array without breaking code
that uses it. As I said, it worked fine before without this
recursion problem.
Since there is no recursion going on there, it shouldn't be a
problem. This seems like a bug/regression.
An indirection does not help.

Which version of DMD exactly? This works in DMD git.

I don't remember what I was using before, I think 2.064. I just
upgraded to the latest 2.065.2 today and tried to compile some
old code and got all these errors. The code was working fine
before. Obviously I could have done something that I forgot but
the errors are saying the templates are recursive as if the
method doesn't work, yet it worked fine before.
