Not a fact, Andreas.

One of Valentina C++ developers have point me that when he use BitSets he
can get speed of query up to 100 times faster.

Parser really can take MANY time, Andreas.
Not only because of text. Also optimizer, planner.
With Bitsets developer __SOMETIMES__ can write VERY optimal plan.

The bigger language parser can understand then longer path to find tokens.
Also, note, that if size of Valentina kernel itself have about 0.6-0.8MB
The Parser looks to get 0.5MB self. Not bad, yes?
