I like that idea too, but what I like even more is the bold originality in it. I think hackers who make these new programming languages should try to be original, and experiment with weird things that actually help them solve whatever problems they feel they have during development, because language is pretty much a programmer&#x27;s user interface.<p>And also this particular feature is close to my heart, because what I would like to see as a feature(s) in programming languages that the programmer would only supply the data schema, and compiler selects the actual data structure based on run time performance characteristics of the program.
