To recap:

Special case code is evil.
Are there properties that a programming language must possess that enable programmers to write code that is free of special case code?
Is it theoretically possible to never have to write special case code?

Are you suggesting that, control flow constructs like "if" in the programming languages should be deprecated? If that is so, I strongly disagree.

Please take for example, following logic (written in pseudo-code),

if (age < 15) {

// do something

}

else if (age >= 15 and age < 30) {

// do something different

}

else {

// do something else

}

The above example, is a specific functional implementation driven by a real world requirement, that can only be implemented by programming constructs like "if".
