That optimization came with 5.10.

From man perl5100delta:

       Single char char-classes treated as literals
           Classes of a single character are now treated the same as i
+f the
           character had been used as a literal, meaning that code tha
+t uses
           char-classes as an escaping mechanism will see a speedup. (

That optimization came with 5.10. That explains why I couldn't find it. I was looking in the wrong place. I guess that this is another of those features--like defined-OR--that was discussed for a long time prior to actually making it into a release.	[reply]
