Description
Both our and babel's output emits (0, expr)
in many places to unbind the this
from the call that's about to be done. Ergo, the 0, expr
pattern is not without side-effects, and is, in fact, a very highly used pattern that we probably shouldn't issue an error on. It's probably OK to special-case the literal-zero LHS as a signal to silence the error.
