The whole codebase must pass the parser before it even considers 
what is in there. So new syntax cannot be detected through this 
or version or anything else.... unless the code is quoted.

If the code is in quotes - as a string - then the parser doesn't 
look at it until it needs to. So you might be able to detect 
using mixin.

__traits(compiles, mixin(" your code here"))
