What are Comp language tags?

Hierarchical named values you define and extend, used as booleans, control flow, units, types — basically keywords on steroids, avoiding string pitfalls.

How do you define and use Comp tags?

!tag name {subtag1 subtag2} in a module; use as name.subtag or shorthand if unique. Extend internals without polluting originals.

Will Comp tags replace enums in other languages?

Not soon, but they'll inspire — hierarchical, extensible, serializable wins over flat enums.
