I Absolutely agree ... which is why I put the smiley there.

What's behind this guess ?

Hmmm. Boost does refuse to make any assumptions, and therefore
requires human intervention in quite a few cases. Maybe default
assumptions could be built into Pyste. Maybe they already have; it's a
while since I looked at Pyste.

And I also suspect that, in practice, there will be a fairly low limit
on the size of library that Boost can wrap, because of compile-time
memory consumption. ISTRT wrapping about 20-30 methods taken from
about 5 classes used up half a Gb of RAM. So you probably don't want
the throw Boost at a whole library indiscriminantly.

Having said that, I recall that was some utility being developed to
split the compilation into small submodules, as an attempt to manage
the memory explosion.
