Define how booleans should work

[Flaque]

The Unix command line already comes with a /bin/true and /bin/false that return "true" and "false" strings respectively.

This begs the question, should booleans be true and false? If they are, should we rely on the /bin versions of them? Are they just functions? Or are they part of the grammar?

[Flaque]

If they were not part of the grammar, and instead were just the *nix functions, we would not be able to use them inside of function parameters without parenthesis.

Example:

myFunc true # this errors out
myFunc (true) # this is okay

[Flaque]

If they were part of the grammar, then it would add another special case *nix command like echo. It also asks other questions:

Does true evaluate to a string or a true boolean type? Normally *nix functions would evaluate to strings.
