[GiNaC-list] list of list

[Jerome BENOIT]

Hello,

I have just tried: it does not work as I want.

In Maple,

my_list := [
	1,
	2,
	3,
	4,
	5,
	NULL];

gives the list [1,2,3,4,5] .

The idea is that inside a script the elements of the list
can be easily commented or uncommented.

my_list := [
	1,
	2,
#	3,
#	4,
#	5,
	NULL];

gives [1,2] .

can we do that with GiNaC ?

Thanks in advance,
Jerome
