Easier way?, cumulate sublist

i have got it working … to get a sublist cumulate,

but i get the feeling there is an easier way.

there is still a small error in this … list.scan seed can’t be the first element… with each group it adds this seed first… i want to just accumulate all

Hi @Arno_De_Lange ,

Something like this?
