Therefore let's invent some new keywords, ones that are unlikely to clash
with user declared identifiers ...

Coined words! Wow - now there's a thought!

brillig = invariant data
slithy = head const
mimsy = read-only view

...with apologies to Lewis Carroll

And that would give us lots of other lovely keywords to play with! Oh my - frumious, vorpal, uffish, whiffling, tulgey. The possibilities are boundless!
O frabjous day!
