Type checking

• Type checking is really a pain. I hate it when I have to add an F to the end of a C# constant to make it type check.
• On the other hand, I absolutely love type checking. It saves me countless errors caused by switching types.
• As typing is weird to the typical person, a lot of scripting languages are typeless.
• That is, everything has the same type.
• That means you can assign a double to a variable and then a string to that same variable.
• This can cause all kinds of funny errors.
• What happens when you add two to "dog"?
• This is one class of error that can really cause problems in scripts.
• There are others.
