Typos are extremely hard to prevent in dynamic data structures since validations need to be implemented at the point of use instead of at the point of creation/definition of the structure. What would stop the developer from writing the typo in their validation, as José did in his example?
It seems to me like if the goal is to prevent typos then a struct would be the way to go. Kurtis Rainbolt-Greene <[email protected]> schrieb am Mi. 30.
