Yes, I know that. The reason I've used them is, of course, they seemed to be
more convenient than alternatives.
I'm writing a parser generator. From the input grammar, which is a string, I
create some tables - nonterminals, rules... Then I build some functions, which
essentially lookups in yet other tables, calculated along the way. The parser
driver maintains some other tables. It's certainly possible to pass them all
around, just not very convenient.
I've done some restructuring already, and don't see immediately how to further
simplify structures - without performance penalties, which (prematurely)
weren't hailed much by, IIRC, Knuth.

Thanks for tips. I'm not sure I know what J session manager is; I'm just
developing with J console and an *.ijs windows open.
