Answer:
I think you need:

Regexp thing = regexp "\\."

The backslash itself has to be escaped, and you need the regexp function to turn the string into a regexp.

So I was trying to match against a period in a regular expression. Normally (like in perl) you escape the character with a backslash. So:

Regexp thing = "\."

But this doesn't seem to work in DXL even though the manual uses it as an example of what the \ (escape) character is used for.

I can use a set operator, [.] to make it work, so I'm not blocked from doing work.

Is this a bug? Should I log it?

Gah! I can't believe I forgot that. Thanks Paul for pointing that out! I was just following the fine manual...
