If you need keys or values you have .keys .values, .byKey,
.byValue (the first two are eager). If you need both you are
out of luck, and if you want to write safe code it's better to
use a foreach loop. If you want to live dangerously you can use
a test.byKey.zip(test.byValue).
Take a look in Rosettacode, there are examples for all of them.

Sorry, i wasn't very clear.
I wanted to know if there a way to lazily change the look up
operation
eg:
assert(test[1]==1);
assert(test[2]==2);
