varray's do not have any recursive function calls, and the methods tend to
be simple. For that reason, they are typically all inlined, eliminating
the parameter passing completely...

[LLVMdev] repeated recursion with "frozen" arguments
...f C-example (see S2.) we just made a
lexical closure in respet to variable `x'. (And by analogy,
in C++ example we could consider similar optimization which
in a sense is a lexical closure in respect to `this')
Now, Chris, please locate the point where I am unclear :)

you are right.
However, my classes for spectra analysis I deal with should be as
fast as valarray...
