I think the common intuitive rules regarding escapes in regexes are as
follows:
1) Unescaped punctuation usually has special meaning (so people often
escape all punctuation literals)
2) Unescaped letters are literal
3) Escaped punctuation is literal
4) Escaped letters have special meaning
Therefore, I think that std.regex should throw on unrecognized *letter*
escapes. It's very likely that the user might be trying to use a character
class or feature from another regex engine, but unsupported by std.regex.
