Help Petit Parse

Hello,
I can not manage this syntax that seems to be simple.

MyParser parse: 'A123A123' -> '123123'
not: #('123' '123')

(#word asParser , #digit asParser plus flatten ==> [:node | node second])
star parse: 'A123A123'.
-> #('123' '123')

(#word asParser , #digit asParser plus flatten ==> [:node | node second])
star flatten parse: 'A123A123'. -> 'A123A123'

Thank you.

(((#word asParser , #digit asParser plus flatten ==> [:node | node second]) plus) ==> [ :node | '' join: node]) parse: 'a123a123'
=> '123123'

probably there is a nicer way. ;)

That is indeed the solution.
