Emmm ...
Actually that's how it should work. It's not a bug.
What the gem actually does is opening the files where you have defined a 
method and extract the lines of method definition.
When you define a method in irb it's not saved in any files. This means 
we have now way to extract its code.
The same problem occurs when you define a method using eval method. The 
method is defined in a string variable (memory) not in a file.
Provided that the above cases rarely happen in a real application, we 
can say that this is not a problem with Detective.
