I'm starting out with LPeg but struggling with inverse matching on a set.
As an example, trying to match a substring without ';' or ',' chars
patt = (-lpeg.S";,") ^ 1
Fails with "loop body may accept empty string"
Plain -lpeg.S";," does the right thing for the first char, so why
doesn't ^ 1 extend that for longer strings?
