I noticed some nits about the way tokens are computed:

• A few assignment operators ( ..= ^= >><= >><= ) seem to cost 2 tokens instead of 1 (all other assignment operators cost 1)

• There seems to be logic that checks the token before '-' to determine if the '-' is a unary operator or not, but it doesn't seem to check newer operators (like &, |, etc.) and thus -1 is considered 2 tokens in things like "a & -1". (Even though it's 1 token in "a + -1")

Good nits, thanks @thisismypassword

I think this is everything:

Missing in the first category were:

..= ^= >><= <<>=

Missing in the second category were:

\ & | ^^ << >> >>> >>< <<>
