At what point is "Unevaluated" stripped?
For instance, in the following, unevaluated is stripped even though
arguments are not evaluated
a := Unevaluated[2 + 3]
So a:=Unevaluated[2+3] and a=Unevaluated[2+3] seem to work the same
OwnValues doesn't show that a has an Unevaluated wrapper, even though
a /. OwnValues[a] results in Unevaluated[2+3], why is that?
Is there any place that documents at which point OwnValues comes into
evaluation? For instance, setting a high level trap (Robby Villegas'
technique) on Set/OwnValues/Replace/ReplaceAll shows no trace of
Is OwnValue application equivalent to
