FilledSmallSquare Unevaluated[expr] represents the unevaluated form of expr when it appears as the argument to a function.

FilledSmallSquare f[Unevaluated[expr]] effectively works by temporarily setting attributes so that f holds its argument unevaluated, then evaluating f[expr].

FilledSmallSquare Example: Length[Unevaluated[5+6]] LongRightArrow.

FilledSmallSquare See Section 2.6.5.
