local_constant_names() public

DEPRECATED: Use local_constants instead.

Returns the names of the constants defined locally as strings.

module M
  X = 1
end
M.local_constant_names # => ["X"]

This method is useful for forward compatibility, since Ruby 1.8 returns constant names as strings, whereas 1.9 returns them as symbols.
