[CM] variable arguments to definstrument?

[Steven Jones]

Is it possible to have variable argument count with definstrument (under 
guile)?    What I have in mind is something like the following two forms

(definstrument (foo :key a b c ... :alow-other-keys)

of

(definstrument (foo :key a b c . args)  Where args captures extra arguments.



Thanks
