The meaning of list and prefix can be illustrated so:
k=. ;:'one two one one three'
v=. ;:'v11 v22 v12 v13 v33'
NB. list returns values of the same key
v #~ k = <, 'one'
+---+---+---+
|v11|v12|v13|
+---+---+---+
NB. prefix returns table of k-v pairs with given k prefix
(#&k ,. #&v) (-:"1 k {.&>~ #) , 't'
+-----+---+
|two |v22|
+-----+---+
|three|v33|
+-----+---+
(#&k ,. #&v) (-:"1 k {.&>~ #) , 'o'
+---+---+
|one|v11|
+---+---+
|one|v12|
+---+---+
|one|v13|
+---+---+

qparamKeys is more correct, because qkeys are made when
there was only one collection: (HTTP) keys and params (values).
Now having cookies and headers, etc. it's better to keep them
separate. At this point it would be reasonable to deprecate
and then remove qkeys.
