Description

The 3.0.7 Groovy documentation could be more clear on regex usage with match operators, particularly:

1. It would be helpful to note here that slashy strings are required for the match operator to work.  `foo ==~ "^\s+$"` will never work.  I know there's a section dedicated to slashy strings; it would be helpful to have a footnote here.
2. This section could benefit from a better example than `m = text ==~ /match/`.
