Comment (by dmsnell):

 Thanks @jorbin - I tried to do that but apparently failed to communicate
 it well; sorry.

 This was motivated by the needs of the HTML API for properly decoding HTML
 named character references, and the [https://github.com/WordPress
 /wordpress-develop/pull/6387 linked PR] demonstrates using this class for
 that purpose.

 The best performance characteristics I could come up with using existing
 mechanisms were over nine times slower than with this optimized lookup.
 The decoder itself is required because PHP is unable to accurately decode
 the HTML entities according to the specification, partly due to its legacy
 of using an XML parser, but also partly due to its interface which doesn't
 acknowledge the more complicated rules in the HTML spec.

 The linked PR contains substantially more warrant for the decoder, as well
 as benchmarks and performance notes comparing different considered
 approaches.
