Yes, I too think this is a bug.
PEGs that match something after the char class matching part even fail,
which is definitely not correct: compare in a buffer containing " a":
(peg-run (peg (* [blank]) "a"))
vs.
(peg-run (peg (* (syntax-class whitespace)) "a"))
The fist one matches up to the "a", the seconds doesn't, but should.
I CC Helmut Eller, the author of peg.el.
Michael.
