Why is \ the only character that could work? Because it's unused? What about
for examole the tilde (~) or the exclamation mark (!)? - both of them are
prefixes only, so neither a!b nor a~b will conflict.

On the backslash: It'll be a bitch in places where you need the class name
as a string (reflection) because \ needs to be escaped withing a string.
Think: How many backslashes do you need in a regular expression using double
quotes to represent a single backslash (try to answer this question without
trying it out. Was it two? Three? four? Six?)
