Variants

`Match`	Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that a match of the pattern has been found at `haystack[a..b]`.
`Reject`	Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that `haystack[a..b]` has been rejected as a possible match of the pattern. Note that there might be more than one `Reject` between two `Match`es, there is no requirement for them to be combined into one.
`Done`	Unstable (`pattern` #27721) : API not fully fleshed out and ready to be stabilized Expresses that every byte of the haystack has been visted, ending the iteration.
