It will be implemented, see #24.
I'm curious about your use case, could you say a few words about why you need this feature?
I use negated character sets all the time with other lexer generators; most of my important tokens involve negation. For example, "starts with & and then is followed by anything other than a number or colon or space", so that "&x_0=é(y)" is a token.
Thanks for the example. I'm closing this as duplicate of #24.
I noticed that negated character sets are not supported? Is there a reason?
