Ouua, you're suggesting so many languages.
I've had already a little of smalltalk prolog and lisp. As more often I
read, the more I consider goint towards one of the icon family. Dylan and

them. I never heared about K or lua. Just KBasic.  J shall be as APL just
using latin chars. Oh yea....  Nice day!
