The help on Regex states that:

" These escape sequences can also be used within a
character
class. For example, `[\l_]' is the same as
`[a-zA-Z_]'"

Two errors here:
\l actually matches any letter, including international
and
accented ones. I'm guessing it is locale dependent like
it is in Perl.

At least it has the same limitation, causing error #2:
using it to construct character classes does _not_
work.

Correspondingly for \L.

    Oops, part two is wrong. You _can_ use it in character classes.
    The first part about the locale still stands, though.

    Well, if the beta branch is certainly open
    to documentation fixes ...

    Just committed a fix to help.etx.
    Can be closed.
