Why is Hungarian notation bad?

Some potential issues are: The Hungarian notation is redundant when type-checking is done by the compiler. Compilers for languages providing strict type-checking, such as Pascal, ensure the usage of a variable is consistent with its type automatically; checks by eye are redundant and subject to human error.
