wrapping these classes into R, if the wrapping design is class-oriented we
should have like 100 objects. At the same time, if the wrapping design is
function-oriented we have like 10`000 objects which are too lazy for lazy

I think the reason, as Uwe already said, is that you have to load
the lazyload index file, and in your case that file is likely to
be as large as the R file itself.

4Mb R file just containing .Call()s? Never seen something like that.
If these are all very small functions, lazy load won't be of that
advantage, because you have to load the index file anyway.
You know, R including all base and recommended packages has just ~ 6Mb of R
code. Are you really sure
This has been fixed and a bug in 2.0.1.

I have just compiled R-base 2.1.0 using the spec-file for SuSE (slightly
