Interrogate
Interrogate attempts to bring Scheme-like class predication to Ruby. It provides an alternate syntax using Module#===
.
>> String?("Hello")
>> trues
>> Symbol?(:World)
>> true
>> Float?(1.0)
>> true
You can "interrogate" multiple objects as well:
>> String?("Hello", :World, 1.0)
>> false
>> String?("Hello", "World", "1.0")
>> true
