-- The quasiquoters exposed by this module support the CUDA extensions, including CUDA-specific declaration specifiers and @\<\<\<…>>>@ kernel invocation syntax.
--
-- It includees partial support for C++11 lambda expressions syntax.
--
-- Support for lambda-expressions has the following limitations:
--
--  * the capture list must either be empty or have only the default capture mode specifier;
--
--  * the return type cannot be explicitly specified;
--
--  * the package supports C language, not C++, therefore lambda parameter list and body must be in valid C syntax.
--
-- Examples of lambdas supported by the 'cexp' quasiquoter:
--
-- > [] (int i) mutable {}
--
-- > [&] { return 7; }
--
