What are some practical examples of dependent types?
Dependent types are types that depend on values. A common example is in programming languages like Idris or Agda.
Can you give me a specific example in Idris?
Sure! In Idris, you can define a vector type that depends on its length, ensuring that operations on vectors are type-safe.
How does this improve type safety?
It allows the compiler to catch errors related to vector lengths at compile time, reducing runtime errors.
Are there any real-world applications of this?
Yes, dependent types are used in formal verification, ensuring software correctness in critical systems like aerospace.
