Thread::Backtrace::Location

The Location class is used by Kernel#caller_locations to store information of every call frame in a call stack. Instances of this class can store information such as:

The path to the file where the frame originated from
The name of the context of the frame (method name, "block", etc)
The line number where the frame originated from
