erl rejects FQN that begin with a digit

This one is probably a really quick fix...
It seems Erlang doesn't like domain names that start with digits, in my
case, the domain "8fun.net"
* 1: syntax error before: 8
()6> tut17:start_ping(). << Notice
the 8 is gone
()7> tut17:start_ping(). << 8 in
the middle works
()8> tut17:start_ping(). << 8 in
the end is fine, too
Domain names that begin with a digit are legal and should be accepted.
Use any FQN that has a domain name that begins with a digit.
R14B built on OpenSuSE 11.3 from source, Windows XP SP3 from R14B binaries
Probably some code is looking to categorize a string based upon the first
character, when in reality, domain names can be represented by the RE
[a-zA-Z0-9]* or the C function isalnum(). Domain names don't need alpha
characters at all in the part before the TLD, e.g. 45.com
I created a simple internal LAN using the domain name of "8fun.net"
I've got DNS and DHCP working on this and I have two hosts, "test1.8fun.net"
and "test2.8fun.net" using 192.168.0.10 and .11 respectively. They can ping
each other by IP or hostname, and all is good with the world.
I started one with "erl -name host1" and I'm greeted with:
Erlang R14B (erts-5.8.1) [source] [64-bit] [smp:4:4] [rq:4]
Eshell V5.8.1 (abort with ^G)
No problem here.
Now, I want to send a message to a process, and I used the tutorial 17 to do
so (http://www.erlang.org/doc/getting_started/conc_prog.html , section 3.4).
This exports start_ping/1, where the first argument is the name of the node.
In short name mode, this works great, but in long name mode, Erlang chokes
on the FQN.
