the co operator

8.20: adda/co/the co operator:
. as shown in chapel,
instead of declaring a block to be a coprogram,
any stmt can be run as a coprogram with:
co stmt;
-- stmt can be procedure literal;
[8.28: I'm wondering why this couldn't be
obvious to the compiler
or to an llvm-type runtime .]
. co { set of stmt's}
-- runs each element in a set in parallel;
var's can be declared sets of stmts .
