Are we talking about its inclusion or whether it is stable in R12B? Here
is my Debian Lenny system with stock erlang (R12B-3):

--

Erlang (BEAM) emulator version 5.6.3 [source] [64-bit] [smp:4] [async-threads:0] [kernel-poll:false]

Eshell V5.6.3  (abort with ^G)
1> Foo = "Hello World! 122.42".  
"Hello World! 122.42"
2> re:compile("[0-9].[0-9]").
{ok,{re_pattern,0,0,

                  ...>>}}

In the readme[1] for the version I'm running, OTP-7181 indicates it is
introduced (experimentally at least?) in that version.
