 the first character is a capital letter ==> this is a constant

pigeon% ruby -e 'p Object.const_defined?(:Array)'
true
pigeon% 

 or

   Object.const_defined?(:Array) && Object.const_get(:Array).type == Class

 be carefull with this

pigeon% ruby -e 'p Object.const_defined?("File::Stat")'
false
pigeon% 

pigeon% ruby -e 'p File.const_defined?("Stat")'
true
pigeon%
