I'm a relatively novice regex user. Could anyone explain to me why someone might use an expression like `.(?:.=.*)` ? What is the meaning of the group if it's boundary could be placed in any number of places? Hope that makes sense.
It can be useful depending on how the engine handles the match. The non-capturing group is the important part, the .* is just there so that the 'full match' isn't just an empty string, but contains the whole line the rule is being run against
