If you just want to do the replacement over the selected text,
you can do the literal substitute:
:'<,'>s/\%V\w\+\%V/\u&/g
or, if your selection starts/ends in the middle of a word and you
don't want to effect them, you can riff on
:'<,'>s/\%V\<\w\+\>\%V/\u&/g
adding/removing "\<" and "\>" as desired. Any of these can
pretty easily be mapped, e.g.
:vnoremap <f4> :s/\%V\w\+\%V/\u&/g<cr>
If you want to take the selected text, pass it to this
transforming function, and then assign it to a variable without
altering the in-line text, you'll have to grab the selection
either by yanking it to a register, or by using getline() or some
such function (likely in a loop). That gets a bit messy if you
don't yank it to a known register.

PS: yeah, John caught my "just a little change after I copy &
paste" flub where I previously had used \(...\) to capture things
and \1 referred to them. Sorry if it caused any confusion.
