Are you sure, it was '[1,' '2,' '3]' and not ['1', '2', '3', '4']?

If it were, it would be really strange, unbelievable.

['1', '2', '3', '4'] would be normal, when you use
a list (it definitely is one!) in e.g.:

  <dtml-var "_.getitem('toks')">

as a list (of cause) can not be part of a generated HTML page.
It must be converted into a string. And the above
it the string representation of a list.

To get the representation, you seem to favour (though
I do not understand why), you could use:

  <dtml-var "_.str(_.getitem('toks'))[1:-1]">

This make the string conversion explicitly ("_.str")
and then keeps the slice "[1:-1]" which means
everything beside the first and last character,
i.e. you chop the '[]'.
