URI::Params::Serializable::EmptyIndexForNonScalarArrayParamError
Inherits URI::Params::Serializable::Error / Exception / Reference / Object
Raised when a non-scalar type has a empty ("[]") index in the query.
Complex (i.e. non-scalar) objects require explicit numeration for their instances, e.g.
if foo is Array(NestedParams(a : Int32, b : Int32)), then foo[][a]=1&foo[][b]=2
makes no sense, because it's not clear whether is it the same object.
