Rangeatype
Rangeatype is a conceptual type system feature that associates a data type with an explicit permissible value range. It is used to express constraints such as numeric bounds or ordered intervals directly in a type declaration, allowing compilers, runtime systems, or analysis tools to verify that values remain within specified limits.
Rangeatypes can be enforced statically, dynamically, or by a combination of both. Statically checked rangeatypes enable
Common uses include input validation, preventing overflow, documenting assumptions in APIs, and enabling more aggressive optimization
Limitations include increased complexity in type inference, potential runtime overhead for checks, and the expressive limits
