It is more or less trivial to extract anything from $args using a 
regular expression.  And the same applies to things like 
"foo$bar=123", or any other fancy character you want to use in the 
query string.

Alternative solution would be to avoid such naming, and use 
aphanumeric plus "_" as directly accessible via $arg_* variables.
