I think we should reserve single quotes, double quotes, tilde, and
backslash in addition to the parenthesis, ampersand and pipe that are
already used. If we need more special characters in the future we have the
option of using backslash to change their meaning. For example, we could
later decide that \^ means "exclusive or", while ^ is the literal carat
character. See for example vim's search and replace syntax:

+1 Dave, a little internationalization support never hurt anyone. Or
does it only look at a single byte instead of a character?

It's byte wise, so extended Unicode would bide a performance hit.

This is a revival of our discussion we had before. On the one hand,
enabling is great. However, we really want to keep some characters reserved
for extended operations.
