class RegexIterator : StreamIterator!(char) #
Iterate across a set of text patterns.
Each pattern is exposed to the client as a slice of the original content, where the slice is transient. If you need to retain the exposed content, then you should .dup it appropriately.

These iterators are based upon the IBuffer construct, and can thus be used in conjunction with other Iterators and/or Reader instances upon a common buffer ~ each will stay in lockstep via state maintained within the IBuffer.

The content exposed via an iterator is supposed to be entirely read-only. All current iterators abide by this rule, but it is possible a user could mutate the content through a get() slice. To enforce the desired read-only aspect, the code would have to introduce redundant copying or the compiler would have to support read-only arrays.

See LineIterator, SimpleIterator, RegexIterator, QuotedIterator.
