* re.c (rb_reg_expr_str): need to process backslashes properly.

* object.c (rb_any_to_a): declare Object#to_a to be obsolete.

* object.c (rb_Array): do not convert nil into [] automagically.

* object.c (rb_Integer): use "to_int" instead of
  "to_i". [experimental]

* object.c (nil_to_f): new method.

* object.c (rb_Integer): Symbols and nil should cause error.

* object.c (rb_Float): nil should cause error.
