Mma 3.0 has a new Attribute called SequenceHold.
As far as I can tell this Attribute has no useful application.
However there are exactly nine built in functions
that have this Attribute. They are:
Rule
RuleDelayed
Set
SetDelayed
TagSet
TagSetDelayed
Timing
UpSet
UpSetDelayed
I used a method in Dave Wagner's book to get the above information.
In what way would things fail to work if these function didn't have this
Attribute?
How did ealier versions get by without SequenceHold?
