Something like this:

writeln(tokenize(sourceCode).filter!("a.type > 
TokenType.STRINGS_BEGIN && a.type < 
TokenType.STRINGS_END")().map!("a.value")().joiner("\n"));

I'm booted into Windows at the moment so I haven't tested that, 
but it should work if you just want a dump of all the strings. 
The line-of-code feature works in a similar way.
