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".

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

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.

Yes, sorry.

In dmd 2.066 this too could work:

alias Array(T) = std.container.Array!T;

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.

That just gives more errors.

I'm not using 2.066 though...

I will revert back to the dmd version I was using when it worked... Hopefully someone can make sure this is not a regression in the mean time... (seems like it is and I don't want to get bit again later on when I upgrade)

That template and its instantiation work fine for me on both 2.065 and 2.066b1.

Ok, I do not know where this error creeped in at. I do know at one point the code was working fine without any changes I believe. (it's possible though I messed something up)

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.
