To check what @some_var
is, I am doing a
if @some_var.class.to_s == 'Hash'
I am sure that there is a more elegant way to check if @some_var
is a Hash
or an Array
.

You can just do:
@some_var.class == Hash
or also something like:
@some_var.is_a?(Hash)
It's worth noting that the "is_a?" method is true if the class is anywhere in the objects ancestry tree. for instance:
@some_var.is_a?(Object) # => true
the above is true if @some_var is an instance of a hash or other class that stems from Object. So, if you want a strict match on the class type, using the == or instance_of? method is probably what you're looking for.
