asProxyTypeOf :: a -> proxy a -> a Source #

asProxyTypeOf is a type-restricted version of const. It is usually used as an infix operator, and its typing forces its first argument (which is usually overloaded) to have the same type as the tag of the second.

data KProxy (t :: *) Source #

A concrete, promotable proxy type, for use at the kind level There are no instances for this because it is intended at the kind level only
