you mean when you want to use an undocumented abstraction and its
usage is not clear?

If so, open it and look for $n variables within _objects_.  $0 will be
a unique argument generated automatically, $1, $2...$n will represent
arguments that a user should provide ($1 = first argument, $2 = second
argument etc).

And the same logic applies if you want to create abstractions that
require arguments...
