r r r r% r( r r r r r ! s r c s f d d } | S)aÞ Decorator to create parameterized rules.
Parameterized rule methods must be named starting with 'p_' and contain
'xxx', and their docstrings may contain 'xxx' and 'yyy'. These will be
replaced by the given parameter tuples. For example, ``p_xxx_rule()`` with
docstring 'xxx_rule : yyy' when decorated with
``@parameterized(('id', 'ID'))`` produces ``p_id_rule()`` with the docstring
'id_rule : ID'. Using multiple tuples produces multiple rules.

Wd S)a Create ply.yacc rules based on a parameterized rule function
Generates new methods (one per each pair of parameters) based on the
template rule function `func`, and attaches them to `cls`. The rule
function's parameters must be accessible via its `_params` attribute.
