Except C++0x lambdas are only monomorphic for now.
Can you be more specific?
In my example '[&a, b]() -> void { /* … */ }', is there is any restriction
on a and b (e.g. thay can't be deduced names)?
The restriction isn't on variables you can capture, but on the types of 
the arguments.

You may not write [&](a) { return a + 42; }
You have to write
[&](SomeType a) { return a + 42; }

Boost.Lambda or Boost.Phoenix will however allow you to write
_1 + 42
which is polymorphic.

I don't really know about ScopeExit, but it can surely do polymorphic 
just as well.
