Updating system without regressing

[Princess Firefly]

Is there a command or a script someone's written that will update packages on your system without regressing to older versions?

Update world is fine unless you have newer packages installed then the 'default' or stable ones. It's so annoying if you do an 'emerge -u world -p' and get a whole list of packages for an 'update' but most of them are older versions then the packages you have installed. Right now I have to do an emerge -s on each pacakge to figure out which version I have installed, then manually update packages one at a time.

Personally I feel update should NOT regress packages unless you specifically say so on the command line, it seems weird that the default action is to remove newer versions of packages.... especially when this can so easily mess up your system (gcc, glibc, etc.)

Anyway, a command like

"emerge -u world --noregress" (or maybe "emerge -u world --pleaseemergedontdeletemynewerpackagesandwreckmysystem")

would be soooo nice.
