of course if you are using a relatively decent language.

- null (that's the most obvious)
- ""
- .length
- 0 (except as a neutral element for addition, in fold)
- 1 (except as a neutral element for multiplication, in fold)
- empty list (except as a neutral element for multiplication, in fold)
- if
- == (especially in Java, where typeless equality kills more kittens than regexes parsing XML)
- goto - I do not know where can one be found though.
