Easy of use is important.

Easy of PORTING 
        v2 => v3,

As well as future  
        v2 => v4        (??)
        v3 => v4

Also is very important. Right?

I just have sent letter-answer to Jim, about pain-points we did have in
v2-v3 porting of our C++/C grammars.

At least will try not loose existed features as reuse()   :-)

Well, we develop DBMS, so our SQL queries are small actually,
But we care about millions possible commands in hot loop

You really recommend us start develop hand-parser ?? :-)

I believe in your book I have read something as
    NEVER do hand-parser :)  to avoid many pain ...


==============
Well, may be somebody know what parser generator is the fastest on this
planet? :-)
