#### What we won't cover
|
||||
Surely a guide written by one person can't be comprehensive. Not only
|
||||
do I have a finite amount of time to share this informatiom with you,
|
||||
but I also don't want to dilute the content of the posts in this series. Furthermore,
|
||||
many things that we'll be using for this tutorial are taught
|
||||
by numerous other sources, and those sources do a better job than I would.
|
||||
So, here are some things that you might want to know for this series,
|
||||
which won't be covered by the series itself:
|
||||
|
||||
* [Theory of computation](https://en.wikipedia.org/wiki/Theory_of_computation),
|
||||
or, more specifically, [automata theory](https://en.wikipedia.org/wiki/Automata_theory).
|
||||
Deterministic and nondeterministic finite automata are briefly mentioned
|
||||
during tokenizing, and context free grammars are used in our parser. However,
|
||||
I don't provide a real explanation for either of those things.
|
||||
* [Functional programming](https://en.wikipedia.org/wiki/Functional_programming),
|
||||
with a touch of [lambda calculus](https://en.wikipedia.org/wiki/Lambda_calculus).
|
||||
We jump straight into implementing the concepts from these.
|
||||
* C++. I do my best to use correct and modern C++, but I'm not an expert. I will
|
||||
not explain the syntax / semantics of C++ code included in these posts, but I will
|
||||
explain what my code does in the context of compilers.

||||

||||
#### The syntax of our language

||||
Simon Peyton Jones, in his two works regarding compiling functional languages, remarks
|
||||
that most functional languages are very similar, and vary largely in syntax. That's
