That's kinda the opposite of what regular expressions do. For example `ab(cd|[xy])` expands to - `abcd`, - `abx` and - `aby`.

If only one value is given the previous character is repeated that often, if two values are given the character is multiplied with each value in the given range. `{,3}` is the same as `{0,3}`. ``` a{3} ``` will expand to - `aaa` Or with a minimum and a maximum value: ``` a{1,3} ``` will expand to - `a` - `aa` - `aaa` This also works with disjunctions and parentheses. **Alternation:** ``` abc|xyz ``` will be expanded to - `abc` - `xyz` **Optional:** ``` abc? ``` will be expanded to - `abc` - `ab` This also works with parantheses: ``` abc(xyz)? ``` will be expanded to - `abc` - `abcxyz` The optional operator has thus the same effect as `{0,1}`.
