I don't know if this is bug or enhancement. It seems there was an attempt to implement it, so I am marking it as a bug for now.
test.c:
__pragma(pack(push, 8))
----
dmd test.c
test.c(1): Error: found `8` when expecting `,`
test.c(1): Error: `=`, `;` or `,` expected to end declaration instead of `End of File`

Where did you see it?

I meant specifically __pragma(pack). Having skimmed over https://github.com/dlang/dmd/pull/13112, I got the impression that __pragma(pack) was supported. I see now that the __pragma token is reserved, but only '#pragma pack' is recognized.
I was able to shut up the compiler with this hack (correctness of '#pragma pack' implementation is not immediately important to me):
#define PP_HASH #
#define PP_IDENTITY(value) value
#define __pragma(args) PP_IDENTITY(PP_HASH)pragma args

That's wrong. __pragma is the identifier for the 'pragma' token. I should be more attentive.
