I like frequency a lot, would be very useful for my NLP code
(although probably I'd replace it with counts and let the user
normalize).
It doesn't perform a normalization (I can add to it few more
functionalities can be added, but not this one), I'll improve its
documentation.
Oh, it's the name that threw me off. I automatically assumed that
"frequency" is normalized counts.
Several of my lazy functions are inspired by:
http://docs.python.org/library/itertools.html
I don't like to show people programs that require my large dlibs to
run, so I hope 80-90+% of my dlibs will be obsolete in D2.
D2 supports immutable data structures, so the D Std lib may gain some
immutable data structures, like finger trees, etc.
Multi-threading, pure functions, immutable data structures, and lazy
computations are forms of computation quite different from the usual
ones done in C. I am sure the current D2 Std lib is using only a
small part of the potential usages of such programming styles :-) I
think some of such usages have yet to be invented (when C++
developers have added templates to C++ surely they didn't know all
the weird and creative usages of them used for example in Blitz++ or
Boost).
Seeing the work of Walter, your work here, and the community in this
newsgroup, and on the other hand seeing how a significant percentage
of computer science is done in academy, and what it produces, I'd say
that there's more innovation and creativity here :-) Lot of CS is out
of the world, not doing useful things, and sometimes not even much
intelligent. Yet, I know many smart folks working in CS in academy,
and I think the design of D2 may be improved by some "hard" thinking
done by that researchers. It's a pity there are so little
communication between the two groups.
Bye, bearophile
That's good to read, and a definite departure from your discouragement
of a few weeks ago. I agree, there are vast areas as of yet unexplored
in D2, and compile-time introspection will open up even many more. (By
the way, I figured how to do introspection, I need to discuss details
with Walter and Sean after which it'll be "a simple matter of
implementation".)
I agree that run-of-the-mill academic work may not be that good, but
then there's a lot of run-of-the-mill practitioner work. I'd say our
work on D2 as of now is not quite up to par with top academic work. The
communication is mostly due to us doing little to publicize D2. But that
will improve starting soon.
