## RE2 compatibility mode
The default behavior of `regexp2` is to match the .NET regexp engine, however the `RE2` option is provided to change the parsing to increase compatibility with RE2. Using the `RE2` option when compiling a regexp will not take away any features, but will change the following behaviors:
* add support for named ascii character classes (e.g. `[[:foo:]]`)
* add support for python-style capture groups (e.g. `(P<name>re)`)
* change singleline behavior for `$` to only match end of string (like RE2) (see [#24](https://github.com/dlclark/regexp2/issues/24))
```go
re := regexp2.MustCompile(`Your RE2-compatible pattern`, regexp2.RE2)
if isMatch, _ := re.MatchString(`Something to match`); isMatch {
