[feature] did you guys knew that "?" is a valid character for function/command name?

[Alex Tweedly]

  Not quite. We specify pass-by-ref by using '@' in the handler 
specification; you can't use it in the calling script as Ben did in his 
example in the email. Ben wants to be able to use the '@' (presumably as 
an option, with no actual effect) in the calling script, to help remind 
him that the variable will/may be changed within the handler.
