The effect on printing makes it worse.  If one package defined a structure
type 'hast-table', even though that violated the conventions, that would
not cause an actual problem unless a second package defined a different
structure type with the same name.

Now, with the record types, a single package defining this type WILL
cause some problems, though they may not be visible for all users.

The constructs that define record types need to check for and reject
the names of built-in types.

Would someone please implement this for master and Emacs 26?
