QuBit: nice idea, but...
Qubit is a nice idea, but it really just shows the holes
in programming languages like C++, Perl, etc. Any
good dynamic language already has the functions
that do the things Qubit does.
For instance, in Lisp languages there are many
mapping functions and so forth that do everything
your lib does. And if you use Lush (a Lisp), you can
compile it all down to C , interface with C libs, and
A language like Lush is much more appropriate for
scientific experiments or research than C++. Thus it
all comes down to using the right tool for the right job.
C++ is not the right tool for physics.
