I am very new using both flex and bison, and to writing compilers. I
am looking for a simple tutorial on creating good ASTs, for use in an
interpreter for a simple language. My attempts thus far although
(somewhat) successful, have proven very slow, and therefore
unusable. I have tried to study the sources of other popular
interpreters, namely PHP, and Perl, but both of those a well beyond my
comprehension. Are there any tutorials on this subject, and if so,
where can I find them? Also, are there any good books that I should
read on this topic, and the theory behind compilers and optimization

Thanks in advance,
