This issue was reported on bugs.ruby-lang.org: https://bugs.ruby-lang.org/issues/11465
The issue appears when using Array#flatten
on an instance of Array
containing instances of a Class that implements method_missing
.
Ruby still calls #to_ary
even when said class implements respond_to_missing?
and returns false
for to_ary
.
Everything works when the class also overwrites respond_to?
.
- Is it expected that
respond_to_missing?
has no effect in the scenario above? - Should a possible workaround rather define a
respond_to?
method or overwriteto_ary
and returnnil
?
