alias_method :pp_callstack, :caller
# Parse a caller string and break it into its components,
# returning an array. Returns:
# * file (String)
# * lineno (Integer)
# * method (Symbol)
#
# For example, from irb,
#
# call_stack(1)
#
# _produces_
#
# [["(irb)", 2, :irb_binding],
# ["/usr/lib/ruby/1.8/irb/workspace.rb", 52, :irb_binding],
# ["/usr/lib/ruby/1.8/irb/workspace.rb", 52, nil]]
#
# Note: If the user decides to redefine caller() to output data
# in a different format, _prior_ to requiring this, then the
# results will be indeterminate.
