Well alright, in the first line, the "-" might be part of the number.
Replace "3.4" with a variable and it does hold:

Yes. A lot.
But there is no conflict. ~ is currently just an unary operator, while
your use would be as a binary operator (are those the correct terms?).
For example, in

Bart Lateur's response summarizes well what I've heard so far
from responses both to the list and privately:
(1) Yes, ~ *is* somewhat used in its current role as the bitwise
negation (complement) operator.
(2) No, that doesn't appear to overlap my proposal for its use

The following is a list of the functionality in the existing Perl5
debugger; this functionality should, of course, be maintained for
backwards compatibility.

You list the particular commands as 'existing functionality'. I think
this is a mistake, even if you didn't mean it that way, if it was just
an artifact of your presentation format. I know that breaking
debugging habits that have been ingrained in at the spinal level may
be hard to break, but t

how about a two-tiered vtable, where a single high bit, if set,
indicates extended handling, or at least consultation of
a different table.

To me this whole thing looks like bike shedding at it's worst at
this point. Please stop and read this
http://www.freebsd.org/doc/en_US.ISO_8859-1/books/faq/misc.html#BIKESHED-PAINTING
and possibly this
http://www.freebsd.org/cgi/getmsg.cgi?fetch=506636+517178+/usr/local/www/db/text/1999/fre
I have a different suggestion:
replace -> with ~
~ is already Perlish for "glues to something related".
That's a different construct than "concatenates."

A vote against the proposed switches, for an unbearably lazy (ok,
