Should a Parameter be const or immutable?
Explore the differences between const and immutable parameters in D programming, and learn how they impact function calls and copying behavior. Understand why const parameters offer more flexibility but can hide immutability information, and discover how templates can optimize parameter handling to avoid unnecessary copies.

Our discussion so far shows that because they are more flexible, const parameters should be preferred over immutable parameters. This is not always true.
const erases the information about whether the original variable was mutable or immutable. This information is hidden even from the compiler.
A consequence of this fact is that const parameters cannot be passed as arguments to functions that take ...
