Operator-functions need to fully mimic real functions

Operator-functions are things like +
or <
:
(+ 2 3)
We need to be able to use them in all the same ways as normal functions, including this following.
Pass by name:
(array.filter <)
Property notation:
(+.apply `(1 2 3))
Spread:
(* ...`(3 4) `(5 6))
Supporting this requires the following components:
- Impostor functions (trivial, partly implemented, see
operators.jisp
) to be embedded with.toString
- Hoisting and embedding mechanism: already implemented, will need a few tweaks for this
- Detect when the operator is referenced a non-standard way (one of the ways listed above), trigger replacement and embedding
- Replacement: replace the operator glyph with the name of the impostor function
- Treat impostor function names as service variables and guarantee that they don’t clash with user-defined names in any scope
