-// Zig has the "usual" comparison operators such as:
-//
-//     a == b   means "a equals b"
-//     a < b    means "a is less than b"
-//     a !=b    means "a does not equal b"
-//
-// The important thing about Zig's "if" is that it *only* accepts
-// boolean values. It won't coerce numbers or other types of data
-// to true and false.
