No Python ...no guffy...
/ ..and python is tooo bitter ..../
Sorry but Python is simply tooo slooow for such a thing.
It seems that C is the almost best option and there are many examples of tokenizers/lexers/parsers/virtual machines
written in C .
Also interpreter writtn in C is in some cases 5 times faster than written in basic compiler
50 to 100 times fster than written in python....yes python is really slow .
I am not sure but i read somewhere that Swift is very fast ...etc..etc..
