std.string.format is using a D-style variadic parameter list. This would 
be a C-style variadic parameter list:

extern (C) string format (int c, ...);

It might just be an old function from D1 when template tuple parameters 
where not just that much.

The compiler disagrees with you:

D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\string.d(2432): Error:
function std.string.format C-style variadic functions are not yet
implemented in CTFE

L2432:
string format(...)

I don't see any other format() overloads in std.string.

That's likely a bug.  D variadic functions push the TypeInfo of each  
parameter onto the stack as well as the parameters themselves.

Unfortunately, it's probably just a wrong error message, I doubt D  
variadic parameters are supported in CTFE.

Yes, that is not a C-style variadic function.

std.metastrings.Format wouldn't be what you want, would it?

Yep it is, Jonathan mentioned it above.

thunderbird hates me. second time I give an answer made redundant by
orphaned subthread.

I'll counter by giving random unsolicited thoughts on Format:

don't use it for codegen (or any long format strings, I suppose). dmd
chokes on it very quickly.

format specifiers could use positional parameters or something. Last
summer I actually wrote a Replace template to scratch that itch. dmd
choked on it pretty quickly too.

I've got the same problem with most of Jonathan's posts. I use flrn, an 
obsure news reader that nobody here probably knows about, so I thought 
it was just me. It seems that the Reference field in Jonathan's posts 
are unusual and break threads in some news reader.

Would anyone know a solution (either for Elley and me, or for Jonathan)?

FWIW I'm on thunderbird, and all is fine here.
