Subject: Re: Need help for Kernel methods

From the doc: 
http://www.ruby-doc.org/core-2.0/Kernel.html#method-i-caller_locations

caller_locations(start=1, length=nil) → array or nil click to toggle 
source
caller_locations(range) → array or nil

*Returns the current execution stack—an array containing backtrace 
location objects.

*The optional start parameter determines the number of initial stack 
entries to omit from the top of the stack.

*A second optional length parameter can be used to limit how many 
entries are returned from the stack.

*Returns nil if start is greater than the size of current execution 
stack.

Could anyone give me small snippets to understand this methods?

Thanks
