I began to learn with the revised syntax, because I made some annoying mistake due to the ambigousness of the syntax. My very first problem in this road is how to write a simple find_pos function, which returns the first position, which equals to the given element. I can write it in the normal syntax, and of course I can translate it into the revised syntax (BTW: can I convert to lisp or sml syntax?), but the result I get wasn't so nice. So I want to implement in the revised syntax find_pos e l (type 'a -> 'a list -> 'a option), which returns the position of the first element in l, which equals to e. thx Gergo +-[Kontra, Gergely @ Budapest University of Technology and Economics]-+ | Email: kgergely@mcl.hu, kgergely@turul.eet.bme.hu | | URL: turul.eet.bme.hu/~kgergely Mobile: (+36 20) 356 9656 | +-------"Olyan langesz vagyok, hogy poroltoval kellene jarnom!"-------+ .
