If range.end is negative, assigns obj at offset start, retains range.end.abs-1 elements past that, and removes those beyond:
a = [:foo, 'bar', baz = 2]
a[1..-1] = 'foo' # => "foo"
a # => [:foo, "foo"]
a = [:foo, 'bar', baz = 2]
a[1..-2] = 'foo' # => "foo"
a # => [:foo, "foo", 2]
a = [:foo, 'bar', baz = 2]
a[1..-3] = 'foo' # => "foo"
a # => [:foo, "foo", "bar", 2]
a = [:foo, 'bar', baz = 2]
a[1..-4] = 'foo' # => "foo"
a # => [:foo, "foo", "bar", 2]
