Fantastic idea! Let's add this to [1]:
15!:6 y - Memory address of locale entry for (boxed) name
15!:7 y - Set name to address header (e.g. name=:15!:7 header)
I'm not kidding; 15!:6 is a very useful facility and I've found numerous
needs for it.

PS: A little J archaeology reveals there used to be a 15!:12 . Here's line
103 from an ancient version of JMF.ijs:
x=. 15!:12 y. NB. 3 col integer matrix
Does anyone remember what 15!:12 did, or what its inputs and outputs were?
