Zig Boolean Enums

Some of my thoughts on using enums in place of bool, adding a way to opt-in to an implicit conversion could have some benefits.

Zig enums provide a convenient way to represent dual-state values (booleans) with domain-specific names. An example of this is std.builtin.Signedness:

const Signedness = enum { unsigned, signed };

Lazy Dependencies Today

• Configure build (build.zig's build fn is invoked)
• If lazyDependency is ever called during configuration, exit the build runner and resolve the missing dependencies and rebuild/rexecute

Example Usage:

const foo_enabled = b.option(bool, "foo", "Enable foo stuff") orelse false;
if (foo_enabled) {
 if (b.lazyDependency("foo", .{})) |foo_dep| {
