Instances of ParseMap are used with str.translate. The following bound search and match functions are defined: _synchre - start of popular statement; _junkre - whitespace or comment line; _match_stringre: string, possibly without closer; _itemre - line that may have bracket structure start; _closere - line that must be followed by dedent. _chew_ordinaryre - non-special characters.

This is designed to be used with str.translate in study1. Anything not specifically mapped otherwise becomes 'x'.

This will be the start of some popular stmt like "if" or "def". Return None if none found: the caller should pass more prior context then, if possible, or if not (the entire program text up until the point of interest has already been tried) pass 0 to set_lo(). This will be reliable iff given a reliable is_char_in_string() function, meaning that when it says "no", it's absolutely guaranteed that the char is not in a string.

Creates: self.stmt_start, stmt_end slice indices of last interesting stmt self.stmt_bracketing the bracketing structure of the last interesting stmt; for example, for the statement "say(boo) or die", stmt_bracketing will be ((0, 0), (0, 1), (2, 0), (2, 1), (4, 0)).
