hi-

I have a function that receives lists. Lists received are of arbitrary lengths and the number of lists received cannot be known a priori.

I would like to be able to produce all combinations of the lists' elements while preserving the order of the lists. An example follows:

Suppose we have 3 lists:

list 1: (1,2)

list 2: (a,b)

list 3: (#,*,&)

i would like to produce the following:

1,a,#

1,a,*

1,a,&

1,b,#

1,b,*

1,b,&

2,a,#

2,a,*

2,a,&

2,b,#

2,b,*

2,b,&
