is there any progress in NIF? And what is this?

[ASVI]

cool, but I think the info prefix is missing. Like %category, info% Maybe it's 
not needed yet, but it can be used in the future with some ast simplifications.
    
    
    Info ::= '%' Identifier ',' Identifier '%'
    NodePrefix ::= LineInfo? Info? Comment?
