I am probably misreading something. With the code below:

<code>
stop <- function( ... ){
    print ("bla" )
}
f <- function( x ){
    stop( "ouch" )
}
</code>

I am interested in highlighting the first instance of "stop" in a way, 
and the second in another, because it is a function call. So the 
MARK_PREVIOUS seems to be the way to go for separating the token i am 
interested in (stop) and the opening bracket, except I want to further 
analyze the token to dispatch the content to a KEYWORD of my choice, so 
the idea was to delegate its interpretation to another ruleset 
containing the keywords.

If I do a <SEQ DELEGATE="kw">stop</SEQ> then how is the "kw" ruleset 
going to know about whether there is a bracket after or not.

I guess I could match stop[^\(]( with SEQ_REGEXP and then flush away the 
bracket in the kw ruleset, but it seems both inelegant and inefficient 
to me.
