And on that note remember that $(Foo) is simple text substitution
rather than seperate evaluation so

Foo = TARGET.Bar =?= "Flibble"

then

RANK = $(OTHER_RANK) + ($(Foo) * 2)

then it macro expands to 

RANK = $(OTHER_RANK) + (TARGET.Bar =?= "Flibble" * 2)

Then the * binds tighter than the =?= and you get no boost from having
put 
+Bar = "Flibble" in your submit file :)

if you use these macros as expression like properties then either get
in the habit of writing

($(Foo)) * x

or make the macro

Foo = ( whatever )

this should avoid nasty head scratching
