I'd like to work on this just to dip my toes into the project.
Here is the current implementation of nearest_mult8 function →

I'd like to shorten it to sz = (sz + 7) & ~7 and build & run tests along the way.

After playing a bit with enums I can see two possible improvements:

1. The str() function on an enumerator returns its numerical value instead of its name, which would be less confusing
2. Numerical values different from the enum's enumerators can be assigned, leading to an inconsistent state

Examples:

let colors = lang.enum(.red, .green, .blue);
let color = colors.green;
io.println(color);       # prints 1
io.println(color.str()); # prints 1
color = 10;              # no errors
io.println(color);       # print 10, which is not a possible color

I still don't know enough about the internals of the language to know how to fix this, so I prefer create an issue

Need to make test cases for the Compiler and VM to verify their correct functioning, as well as make adding features/modifications easy to test for any breakage in existing system.

The tests must consist of the following components:

• Nil
• Integers
• Floating point numbers
• Strings
• Modules (tests/builtin/mod.fer)
• Language Constructs
  • Conditionals
  • Loops
    • For (tests/multi_loops.fer)
    • Foreach (tests/multi_loops_range.fer)
    • While
  • Continue (tests/multi_loops*.fer)
  • Break (tests/multi_loops*.fer)
  • Functions (tests/facto_*.fer)
  • Return (tests/facto_*.fer)

Standard Library:

• IO
• Vectors
• Maps
• FS
• Lang
• OS
• Ptr
• Runtime
• String
• Sys

Tests will be run using the assert function, as well as using valgrind for memory leak checks.

Also:

• Write a Feral script to execute all the tests in one command (test runner script)
• Add valgrind capabilities in the test runner script

The following things are yet to be implemented in the Feral Book.

• Implement more chapters
  • 7 - Loops
  • 8 - "Member" Functions
    • For
    • While
    • Foreach
  • 9 - "Member" Functions
  • 10 - Modules/Imports
  • 11 - Scopes and Variable Assignment vs Copy
  • 12 - Standard Library
    • 1 - IO
    • 2 - Lang
    • 3 - Strings
    • 4 - Vectors
    • 5 - Maps
    • 6 - FS
    • 7 - OS
    • 8 - Runtime
    • 9 - Ptr
    • 10 - Sys
    • 11 - Builder
• Review existing chapters
• Implement highlighting for Feral code blocks (Highlight.js)

I think the # is abolishing all existing standards in other languages, where all comments are declared by // and /* */.

Hi :)
Even though building Feral isn't too hard, I've created an installer script that builds Feral and its standard library automatically.
I thought it may be a good idea to add it to README.md as an alternative installation option, especially for people who just want to get started real quick.
