State variables can be named `public` and `constant`

[smarx]

These should be treated as reserved words.

public: uint256 # BUG
constant: uint256 # BUG

@public
def __init__():
    self.public = 5

[robinsierra]

Another one is is_contract:

is_contract: int128

@public
def foo():
   i: int128 = self.is_contract  # type error

[fubuloubu]

Some bash magic:

$ { \
    grep -Ioh "\"\([a-z]\+\)\"" -r vyper/ | sed 's/"//g' ; \
    grep -Ioh "def \([a-z]\+\)" -r vyper/ | cut -c 5- ; \
} | sort | uniq
