Subject: Changing outside variables inside a proc

Hello all,

Is there any way to change an outside-scoped object inside a proc? Such
as:

a = "Foo"
b = "bar"
proc = Proc.new { |val1, val2| val1, val2 = "boo", "baz" }
proc.call( a, b )

# a and b are still "Foo" and "bar"

I don't believe this is possible.. but would be very nice for creating a
collect! method for a user-defined object. Thanks

Nate
