This is OT but as OP got lots of useful information already ;).

Actually I much prefer
A === x
to
x.is_a? Array

Proof ;)
Let us assume I am not a native English speaker, surely I prefer the
symbolic name to
the sophisticated auxiliary verb "to be" which happens to be irregular
too, cans I has a Grammar please !!! and the indefinite article "a".
If OTOH I were a native speaker I would be quite shocked that it reads
is_a? instead of is_an?, would I not? (not! is not a method name!, as
name! is not!.... ad infinitum)
Q.E.D.

Seriously #is_a? is more readable for sure but #=== has the advantage
to pinpoint the possibility of using a *case* statement.

Cheers
