(lambda ( . rest))

[Bertalan Fodor]

Hi,

I found this in lilypond-book-preamble.ly:

(lambda ( . rest)

Besides that I can't imagine what that wants to mean, the GUILE doc clearly says:

— syntax: lambda formals body

(variable1 ... variablen . variablen+1)

There must be at least one argument before the period.

It seems clear that GUILE accept that strange form. But not any of my Java-based parsers.

What would you suggest to do with that?

Thanks,

Berti
