Can you parse the d source file during compile time with std.regex?

I know that UDA exist, what I want to know if it is possible to 
create one that prevent certain things like calling certain 
functions in a function body Ie
@custom main()
{
  //function body
  example()//throw error by @custom
}
There is no getRawFunctionBody for traits either, so I was 
thinking about using std.regex to get the string of the function 
body and and then parse that string during compile time.
