E0111 error

Compound assignment with multiple targets

area: parsing (x01xx)
fails the build: yes

A compound assignment (+=, ..=, ??=, …) has several targets, as in a, b += 1. Compound assignment takes exactly one target; write one statement per variable.

Example

× failswowlua

local kills, deaths = 0, 0kills, deaths += 1print(kills, deaths)

✓ compileswowlua

local kills, deaths = 0, 0kills += 1deaths += 1print(kills, deaths)

The compiler reports it like this:

error[E0111]: compound assignment has a single target
  ┌─ src/main.wowlua:2:15
