I don't see anything recursive about it... and the code worked

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;

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.

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.

No errors! Works as expected.

So, WTF?!?!

I guess now I have to attempt to split the code across modules to 
see WTF is going on? Maybe this is a modules issue. I know some 
of the code I'm using deals with module resolution and there was 
some talk in the main forum about changing something to do with 
modules.

Could this be the issue?

D really needs a better fing way to debug templates or improve 
the error messages. I'm dealing with about 20k lines of code 
spread across about 100 modules and the error messages are 
completely useless as when I put all the code surrounding what it 
says is causing the error, I do not get the error.

Realize, this code works fine in 2.064 so it's not a coding issue 
as if something magical with my fingers when I copy the code from 
the modules into a single .d file. Either something was "fixed" 
or something was "broke"... after all the work I spend trying to 
figure out what was causing the problem, I'm just as clueless.

Have you tried dustmite? It can also reduce source code split 
over several files.

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.
