Documentation for method BIND-POS, assembled from the following types:
multi method BIND-POS (::?CLASS: , \new)
Expected to bind the value or container
new to the slot at position
$index, replacing any container that would be naturally found there. This is what is called when you write:
my = 10; := ;
The generic Array class supports this in order to allow building complex linked data structures, but for more domain-specific types it may not make sense, so don't feel compelled to implement it. If you don't, users will get an appropriate error message when they try to bind to a positional slot of an object of this type.
