Bikeshedding here….  What about ` 1+-16 `?  Defines the `+` operator as 
additive scaling, the same as `*` is multiplicative scaling, and allows 
negative numbers.

Hmmm… probably won’t work, unless `+-` is its own token (so `1 +- 16` 
not `1 + -16`), since `-` has an established meaning and it’s been too 
long since I played with lex/yacc to reason this out for real.  And a 
`+-` token is not better than the other options given.
