This lexer is for grammer notations which are similar to
original BNF.
In order to maximize a number of targets of this lexer,
let's decide some designs:
* We don't distinguish `Terminal Symbol`.
* We do assume that `NonTerminal Symbol` are always enclosed
with arrow brackets.
* We do assume that `NonTerminal Symbol` may include
any printable characters except arrow brackets and ASCII 0x20.
This assumption is for `RBNF <http://www.rfc-base.org/txt/rfc-5511.txt>`_.
* We do assume that target notation doesn't support comment.
* We don't distinguish any operators and punctuation except
`::=`.
Though these desision making might cause too minimal highlighting
and you might be disappointed, but it is reasonable for us.
