 A regex declares a string processing algorithm using syntax familiar across a variety of languages and tools throughout programming history. Regexes can be created from a string at run time or from a literal at compile time. The contents of that run-time string, or the contents in-between the compile-time literal's delimiters, uses regex syntax. We present a detailed and comprehensive treatment of regex syntax.
 
-This is part of a larger effort in supporting regex literals, which in turn is part of a larger effort towards better string processing using regex. See [Pitch and Proposal Status](https://github.com/apple/swift-experimental-string-processing/issues/107), which tracks each relevant piece.

This proposal regards _syntactic_ support, and does not necessarily mean that everything that can be written will be supported by Swift's runtime engine in the initial release.

 Even though it is more work up-front and creates a longer proposal, it is less risky to support the full intended syntax. The proposed superset maximizes the familiarity benefit of regex syntax.
