    2828### Qualifier Cast ###
    29 A more restricted (and thus safer) form of coercion is modifiying the qualifiers of a type; C++ has `const_cast` for this purpose, and a similar feature would be useful for Cforall. With regard to syntax, `(requalify const Foo)`/`(requalify Foo)` to add/strip `const` would echo C, but given that the vast majority of uses are stripping const-qualfiers, `(non const)` would be shorter, clearer, easily searchable, and not require the programmer to exactly match the argument type. In this syntax, coercion casts could be used to add qualifiers, or another cast type (say `(with const)`) could be introduced to add qualfiers.
