/* In the future the intention is to split out the C/C++ grammars distinctly
|
|
since they are separate languages. They will likely share a common foundation
|
|
though, and this file sets the groundwork for that - so that we get the breaking
|
|
change in v10 and don't have to change the requirements again later.
