Well, if you want to help me with GSL shell I'm open to accept
collaborators ;-) actually I'm looking for people to help me.
Otherwise, GPL license is great and I'm not planning to make money
with it.

I've given a look to your code. The idea is not bad but still, it is a
trick, a workaround to the problem that index takes just one argument.
My point is to have a plain simple syntax, nothing tricky or awkward.
For the moment I will stick to the slogan "simple is beautiful" :-)
