# Todo:
# - finish tr/// changes
# - add option for even more parens (generalize \&foo change)
# - {} around variables in strings ("${var}letters")
#   base/lex.t 25-27
#   comp/term.t 11
# - left/right context
# - recognize `use utf8', `use integer', etc
# - treat top-level block specially for incremental output
# - interpret in high bit chars in string as utf8 \x{...} (when?)
# - copy comments (look at real text with $^P?)
# - avoid semis in one-statement blocks
# - associativity of &&=, ||=, ?:
# - ',' => '=>' (auto-unquote?)
# - break long lines ("\r" as discretionary break?)
# - configurable syntax highlighting: ANSI color, HTML, TeX, etc.
# - more style options: brace style, hex vs. octal, quotes, ...
# - print big ints as hex/octal instead of decimal (heuristic?)
# - handle `my $x if 0'?
# - include values of variables (e.g. set in BEGIN)
# - coordinate with Data::Dumper (both directions? see previous)
# - version using op_next instead of op_first/sibling?
# - avoid string copies (pass arrays, one big join?)
# - auto-apply `-u'?
# - while{} with one-statement continue => for(; XXX; XXX) {}?
# - -uPackage:: descend recursively?
# - here-docs?
# - <DATA>?
