OK... This error message has me totally confused:
src/com/neuralnexus/nnengine/nodeweb.d(436): function com.neuralnexus.nnengine.nodeweb.nnWebNode.getImmediateChildren cannot access frame of function __funclit9

????

I'm running DMD 0.113 on Linux.

Thanks

Sounds like you're trying to do something strange with a function literal.  Can you show the body of nnWebNode.getImmediateChildren ?

I was going to post it originally, but it's a pretty mundane function. Also of note is that this compiled no problem with previous versions of DMD.  I haven't touched the code in awhile, so I'm not sure when it stopped working.

Hmm... wow, now I'm confused.  Don't see any use of func literals in there at all.  Suddenly I see why you asked about it on the newsgroup. Which line is #436, btw?

And is there a special reason (just something I noted when scanning it and mentally compiling) why 'nnWebNode[] ret' is defined seperately in the if and else blocks?

436 is the first line- the function declaration.

No reason...  I just changed it to see if it made any difference in compilation... it didn't.

Alright.. I've got another clue, although I haven't been able to boil it down to a short test case.

I've got a struct, called "Nodes" and then, first thing in the module, I've got:
Nodes nodes;
To create a global instance of the struct.

Any function that uses this struct seems to fail on this error.

Any suggestions?  Please?

OK... I fixed the problem by modifying that line from:
public Node nodes;
to
public static Node nodes;

Hmm.  Odd.
A) I wouldn't think that would have to be static... but oh well, that shouldn't hurt it any at all.
B) The error message sure didn't give /any/ clues at all.  Obviously, considering my initial intuitive response was, "Oh, something wrong with a function literal?"  I think maybe the compiler misdiagnosed.

Bug.

Strange.

I wonder why the non-static version causes the "funclit" error.

As for the Node struct, perhaps, without the static designation, it can't be accessed properly outside of its module;  the d manual states:

"Static data has only one instance for the entire program, not once per object."

So what does this imply for non-static module level instances of a struct?  Is access to them limited to the module only?  It would be nice to know a few more nitty gritty details here about how the compiler works.

Either it's a misdiagnosed error, or it's a valid error for something the compiler is doing behind the scenes.
