iter, dir_obj, [nil] = lfs.dir( path )
    'dir' is a Lua iterator over the entries of a given directory, where 'iter' 
    is the iterator closure, 'dir_obj' is the invariant state, and the control 
    variable initial value is nil.  Error raised if 'path' is not a directory.
    
    Each time the iterator is called, it returns a directory entry's name as a

How do I submit a bug report for Pharo?

Here's how to submit a Pharo bug report.  Fortunately, GitHub makes it easy and 
straightforward.

Start by surfing to https://github.com/pharo-project, then find the particular 
Pharo project that's involved.  In most cases, you'll probably want the "pharo" 
repo: https://github.com/pharo-project/pharo.  (Note that if you enter a bug 
report in the wrong repo, the devs can easily move it to where it belongs.  But 
do try to get the correct one; it will speed things up for everyone.)

What makes Lua a cool programming language?

* You can mix imperative, OOP, or functional programming styles.
* Can execute as a file, interactively in a REPL[1], or be embedded.
* Highly portable, extensible, and has an excellent C API[2].
* Compact and headless; you add packages to extend capabilities.
* Supports packages and modules[3]; package manager is 'LuaRocks'.

* Dynamic typing[4] & dynamic structures; easily polymorphic.

Tips on getting started with Pharo Smalltalk:

The Pharo Playground & Transcript

The Pharo IDE (specifically, a Playground plus the Transcript) is very useful 
for creating and executing "code snippets" or even entire scripts in Pharo.  
It's very easy to get a Pharo IDE installed and running by just downloading and 
installing Pharo Launcher from https://pharo.org/, cloning a template image, 
then launching the image.

Notes on running ProfStef, the "quick-start" tutorial for Pharo Smalltalk:

Where to find ProfStef

'ProfStef' is a 15-minute introduction to Pharo that's built into every Pharo 
image template.  ProfStef will guide you through a "hands-on" tutorial of the 
entire Pharo syntax in 29 steps, using the Pharo IDE.  To run it, you need to 
open a Pharo image; start by downloading and installing the Pharo Launcher app 
for your host platform from https://pharo.org, then clone any template to make
