It's a non-trivial niche - 'embedded DSLs'. Lua is good for this, and
extra operators can be usefully chosen to map onto domain concepts.
(As long as it isn't a _hundred_ operators - that's way bigger than
normal peoples' working set memory)

Would be rather nice to have a function short-form, but that boat
sailed long ago. This makes Moonscript an even better base for DSLs,
without losing the Lua ecosystem - see end of [0]
