more mset hackery. Parallel assignment.



hi barton,

i'm not understanding what subscrmap is supposed to do ...

 [a,b,c]: [1,2,3]  =>  [[1, 2, 3], [1, 2, 3], [1, 2, 3]]
 [a,b,c]  =>  [3, 3, 3]

after subscrmap: true . 

aside from mset, subscrmap also appears in meval1 
(and nowhere else). i can't tell what it's doing in meval1 either.

for what it's worth,
