Hello,

Which characters are to be escaped:
* inside [] classes
* outside such classes
?

Also, is there for D regexes a "free form" format (where whitespace can be used to present formats more legibly, but must be escaped as literals)?

This is a comment in a regular expression: (?#comment)

The text, "comment", can be replaced with anything including whitespace.  The comment is terminated with ).

Oh, never mind.  I just tested this.  std.regex doesn't support regex comments, apparently.  :(

Though you are probably asking specifically about D:

http://www.regular-expressions.info/charclass.html

std.regex doesn't follow everything so testing usually must be done with D. There is no place to find what isn't supported by D. Filing bugs is of course a good choice.
