Re: [RFC] [PATCH] Provide the ability to write the frame unwinder in Python

As food for discussion,
I know some people use foo:bar in Scheme to separate
the object "foo" from the operation on it "bar".
-> frame-data:read-register
I like having some separator, but I went with what
I thought was the preferred spelling (all -'s).
It's not too late to change gdb/guile to use foo:bar throughout (IMO),
but the door is closing.
