on a second thought, I think that the right syntax would be
expandonce(`macro', a, b, c)
expandonce(`include', `file')
or perhaps
indirq(`macro', a, b, c)
indirq(`include', `file')
The name `indirq' stands for `indir quoted', because expanding once is the
same as returning quoted body of the macro. That's why I said it's similar
to `defn'--in fact, it's the same if the macro body doesn't contain any $.

I remember we discussed this, after I have forwarded you a note from Akim.
But now I think `indirq' is the right control mechanism.
If you wish that all includes return the body quoted, you can do
define(`include_orig', defn(`include'))
define(`include', `indirq(`include_orig', $1)')
and similarily for other builtins.

Maybe `indir_quoted' is just better name than expandonce. ;-)
