Really? I read the first as the macro saying "No, you got it wrong.
Read the docs/source and figure it out." Not the most helpful error
message, maybe, but since macro interfaces are so much more free-
form than procedure interfaces, it's harder to say exactly what went
wrong.
The other error message, on the other hand, has very much an
internal error feel to it.
Thank you for boiling it all down to such a short summary. Syntax --
like it or not -- has a radically different status than values. Most
programmers who approach Racket will NOT have programmed in a world
where syntax is just another library 'thing'. Instead they come from a
world where parsing signals mistakes and when something from the
inside of the parser spills out, it's a compiler bug.
[Of course, it is a compiler bug for us, too, because macros are a
compiler API. But we don't have to be blatant about it.]
