This commit separates `PermissionDeniedError` into two kinds; `Retryable` and `Fatal`. The existing `PermissionDeniedError`s fall into `Retryable`, since permission errors can be resolved by retrying with proper permissions in Deno CLI. The motivation of adding `Fatal` is that in some environments some operations are just disabled; for instance, in Deno Deploy, any write operations to filesystem can never be granted, in which case `Fatal` kind becomes useful.

Deno
Deno
(/ˈdiːnoʊ/, pronounced
dee-no
) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on V8,
Rust, and Tokio.
Learn more about the Deno runtime in the documentation.
Installation
Install the Deno runtime on your system using one of the commands below. Note that there are a number of ways to install Deno - a comprehensive list of installation options can be found here.
Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):

Build and install from source
Complete instructions for building Deno from source can be found in the manual here.
Your first Deno program
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called server.ts
and include the following
TypeScript code:
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
Run your server with the following command:
deno run --allow-net server.ts
This should start a local web server on http://localhost:8000.
Learn more about writing and running Deno programs in the docs.
