I've taken this.

Dropping all this checks is a bit scary, but no test complains so I 
guess we can trust the parser. inlining all this functions are a bit sad 
as this make the code less readable.
However unifying these two code paths seems a noble goal as this will 
reduce code duplication and help maintainance and evolution.

Cheers
