[NTG-context] Making checkboxes

I am trying to define a (paper) feedback form. One of the things I
need is checkboxes. A first stab for this (for example I need also a
start text, but I do one step at a time) is, based on TeX by Topic, a
Texnician's Reference page 106:
    \def\checkBox#1,{\space\space\space\space[\space\space] #1\par}

    \def\checkBoxes(#1,){\xcheckBoxes#1, xxx,}
      \else \checkbox#1,%


    Some text

    \checkBoxes Yes, No, A little bit,xxx


I would expect:
    Some text
        [  ] Yes
        [  ] No
        [  ] A little bit
but I get:
    Some text
    es, No, A little bit,xxx

What am I doing wrong?

Something else: how do I 'eat' spaces between parameters. I would like
to have:
    \checkBoxes Yes,No,A little bit,xxx
    \checkBoxes Yes, No,   A little bit,    xxx
the same result.

And is there a way to know how many parameters a macro gets? Like ${#}
in Bash. That would make things easier.
