262 | # | ||||
263 | # deparse() calls each per-op subroutine with an argument $cx (short | ||||

265 | # a number describing the op's parents in terms of precedence, whether | ||||
266 | # they're inside an expression or at statement level, etc. (see | ||||
267 | # chart below). When ops with children call deparse on them, they pass | ||||
268 | # along their precedence. Fractional values are used to implement | ||||
269 | # associativity ('($x + $y) + $z' => '$x + $y + $y') and related | ||||
270 | # parentheses hacks. The major disadvantage of this scheme is that | ||||
271 | # it doesn't know about right sides and left sides, so say if you | ||||
272 | # assign a listop to a variable, it can't tell it's allowed to leave | ||||
