Restricted quoters

qapply :: Binding -> Binding -> Result Binding

qnum2 :: Quote a => (Scientific -> Scientific -> a) -> Binding

Quote a binary numeric function.

qcol1 :: Quote a => (Text -> a) -> (Object -> a) -> (Array -> a) -> Binding

Quote a comprehensive set of unary functions to create a binding that supports all collection types.

Errors

unexpected :: String -> String -> Result b

typeOf :: Value -> String

Retrieve a consistent type from a Value to use in error messages.
