\stoptabulate
Often frozen commands are redefined on demand and they can be overloaded. Mutable
doesn't mean that a user can change it without consequences, for instance the
\type {\current...} ones. Primitives come with the engine, permanent macros are
the core of \CONTEXT. Noaligned macros are special and dealt deep down when
scanning for alignment specific primitives.
