I was checking web site of the FoundationDB. It says that it was developed on new programming language Flow. In websites it says :
Flow is a new programming language design -- in fact an entirely new programming language paradigm -- that solves the multicore dilemma through ubiquitous, guaranteed-safe implicit parallelization.
The code
itself eventually is being compiled to C++.
What I am thinking about is that would it be possible to have C++ code inside Flow and would it be possible to reuse already existing C++ code/libs ?
