Subject: CONSTANT names...
From: jochem@iamjochem.com (Jochem Maas)

hi guys,

I was mucking around and noticed the following:

define("404_SKIP", 1);

does not give an error and you can successfully get the value of the 
constant by doing:

constant("404_SKIP");

where as doing:

echo 404_SKIP;

gives an error.
as I understand it, i.e. what the docs say, is that the following regexp 
  expresses valid starting chars for the name of a constant (the same 
going for vars):

/^[a-zA-Z_\x7f-\xff]/

so pretty minor thing here but I expected to see the define() throw a 
(fatal?) error, rather than letting me go on.

kind regards,
Jochem
