The Dictionary defines a: as <$0, but in fact the two are not interchangeable.
The challenge is to demonstrate this: write a verb that produces a result when
applied to a:, but gives domain error when applied to <$0 .
test a:
test <$0
|domain error: test
| test<$0
Then, give a correct definition of a: .
