The comptime keyword is only needed in Zig if the code could execute at runtime. It forces compile-time evaluation, but it isn't the only way for it to happen.

The comptime keyword is only needed in Zig if the code could execute at runtime. It forces compile-time evaluation, but it isn't the only way for it to happen. So Zig actually does what you seem to think it should do (and I agree! it's great!): if something can be calculated at compile time, it is. Only when the compiler can't statically deduce a compile-time construct is it necessary to use the `comptime` keyword: in fact, it's an error to use the keyword when the context is already comptime.
