True, but the library compiles on C++03 as well. There are explicit
comments in the docs that indicate the library is most useful when
C++11 lambda functions are available (plus essentially all examples in
the docs use lambdas):

``It is possible to use this library without C++11 lambda functions
but a large amount of boiler-plate code is required to manually
program separate functions to specify preconditions and postconditions
(so using this library without C++11 lambda functions is not
recommended, see No Lambda Functions).''

https://lcaminiti.github.io/boost-contract/doc/html/boost_contract/getting_started.html#boost_contract.getting_started.compilers_and_platforms

So, if I'll push the library in Boost, I'd probably push it as a
non-C++11 specific library that is however most useful on compiler
that support C++11 lambdas.
