vi visual mode action on section

hi, I can use visual mode okay, and I can also use the familiar
:.,34s/^/#
to comment out perl sections, but
I can't use visual mode to achieve the same effect.   I would like to, because then I could select the section and perform actions on it without using line numbers or anything fancy.

alternatively, can a brave soul volunteer to enlighten me as to how I can use the same effect by going to the } which corresponds to the final { on my line.  In other words, that matches the function body.

% matches any (,{,[ character. Place the curser on one end of the block, hit % and you will be taken to its mate, % again goes back.

- go to the beginning of the block you want to comment out
- hit v (enter Visual)
- go to the end of the block
- do ':s/^/#<CR>'

-> job done

that makes no substitution but does manage to highlight the first character of the entire file
:(
I know there's a command that is supposed to operate on the visual section. This command is
'<,'>
which is a range of address from beginning to end of the pattern space.
However, doing
:'<,'>s^/#
too does nothing.
I think it has something to do with using the visual range specifiers but i don't understand how to achieve what I want yet using them.

well, it definitely works on quite a few versions of vim (for example my Debian's VIM - Vi IMproved 6.2 (2003 Jun 1, compiled Apr  1 2004 23:39:33))

the ':s/^/#<CR>' sequence is what you have to TYPE, '<,'> will be added by VI (meaning "Range is current selection")... and please check again the sequence :

:s/^/#<CR> vs s^/# you wrote... you're missing a few /'s

(you obvisouly have to select at least one beginning of line).
