I would like to replace sublists of a list to be replaced by another
list, such that for example the rule
{1,2}->{1,2,3}
wout tranform
{1,2,3,3,1,2} into
{1,2,3,3,3,1,2,3}
Simply gibbin the transformation rule in the form
{x___,1,2,y___}->{x,1,2,3,y}
does not work.
What is the idiom to do what I want?
