In a mixin, I can change the value of a component parameter using
@BindParameter to get a mirror of the parameter and then updating the
mirrored value.

This is fine with the prop: and var: bindings since they are read/write
bindings. If I try this with a parameter which is bound to symbol: or
literal: the update fails with "Binding %s is read-only" (originating from
AbstractBinding).

Is there any way that I can change a component parameter that is bound to
literal: or symbol: from a mixin?
