It’s funny, the exact same logic applies to method and variable names. There’s no compiler that ensures that a method’s name accurately describes what the method does or ensures that a variable’s name accurately describes what the variable represents. Yet nobody ever says “you shouldn’t use descriptive method and variable names because they might be misleading”. And this is hardly academic: I can’t count the number of times I’ve run into methods that no longer do what the method name implies they do.
And yet method and variable names are exactly what people mean when they talk about “self-documenting” code.


I started my career with Visual Basic (3!) and I appreciated the loose typing because it meant I could get going and actually have something running quickly as a newbie. A few years later I switched to C# and saw how an entire class of errors disappeared because of the strong typing. Both have their place, depending on the skill level of the coder and the needs of the application.
