What locale are you in when you start J?
If you're in the z locale, then a=.4 is equivalent to a_z_=.4 and a_test_ will
(failing to find the name 'a' in test) return that value.
Try
18!:5 ''
and
18!:2 <'test'
If the result of the former is an element of the latter, then you've got your
explanation.
