CONSTANT names...

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
