I think it's not the number of tokens that matters, but
whether you have a pattern that can be named and reused.
If you have, name it:
after =: 2 : '(0{v`'''')`:[EMAIL PROTECTED] u (_1{v`'''')`:[EMAIL PROTECTED]'
+ after (-`-:)
+-------+-+--------+
|+-+-+-+|+|+--+-+-+|
||-|@|[|| ||-:|@|]||
|+-+-+-+| |+--+-+-+|
+-------+-+--------+
[EMAIL PROTECTED] + -:@]
+ after -
+-------+-+-------+
|+-+-+-+|+|+-+-+-+|
||-|@|[|| ||-|@|]||
|+-+-+-+| |+-+-+-+|
+-------+-+-------+
[EMAIL PROTECTED] + [EMAIL PROTECTED]
