How to Write Hygienic Rust Macros

Macro hygiene is the concept of macros that work in all contexts; they don't affect and aren't affected by anything around them. Ideally all macros would be fully hygienic, but there are lots of pitfalls and traps that make it all too easy to accidentally write unhygienic macros. This guide attempts to provide a comprehensive resource for writing the most hygienic macros.

Understanding the Module System

First, a little aside on the details of Rust's module system, and specifically paths; it is

#!/usr/bin/env python3
from git import Repo, Commit
list_commits = lambda commits: '\n'.join('  {}  {}'.format(n.hexsha[:8], n.message.splitlines()[0]) for n in commits)

repo = Repo.init('path to bare clone', bare=True, mkdir=False)
refs = repo.refs

# load whole graph
def visit_graph(roots, get_parents=lambda n: n.parents):
    queue = list(roots)

I was drawn to programming, science, technology and science fiction
ever since I was a little kid. I can't say it's because I wanted to
make the world a better place. Not really. I was simply drawn to it
because I was drawn to it. Writing programs was fun. Figuring out how
nature works was fascinating. Science fiction felt like a grand
adventure.

Then I started a software company and poured every ounce of energy
into it. It failed. That hurt, but that part is ok. I made a lot of
mistakes and learned from them. This experience made me much, much

Partial Evaluation, Futamura Projection And Their Applications

What Partial Evaluation Is?

Partial evaluation means to fix some variables in the given code before execution. With a traditional implementation of a compiler or an interpreter, all variables are replaced with its value on each evaluation of that variable. This is because a variable can change at any timing. This is, however, not always true in actual applications. Almost all of large applications has setting variables and data
