Habanero-C++ is a compiler-free work-stealing library (under development), which supports Habanero-C work-stealing constructs. This library implementation is build on top of HClib and OCR. Habanero-C++ makes heavy use of C++11 lambda functions in its APIs. C++11 lambdas avoid the need for compiler support while still retaining the syntactic convenience of language-based approaches.
