in reply to change [A-Z] to U, [a-z] to L with one regex?

You can always use $_:

$_ = "SomEThingWithMIXEDRegiSter\n"; y/A-Z/U/, y/a-z/L/; print;

Yes, this is technically still two expressions, but as others have stated, it'll be efficient, and to me, anyway, the comma operator has good semantic meaning, here, even though a semicolon would do just as well.

Update: Corrected bracket typo in y///. Thanks jwkrahn.
