[gambit-list] Questions about tables.

Marc:

I have some questions about tables.

1. Can there be a function like

(table-update! table key (lambda (#!optional (value default-value)) <whatever>))

instead of using

(table-set! table key ((lambda (value) <whatever>) (table-ref table key default-value)))

It would seem to avoid one table lookup for the key.

2. I presume that the table can get messed up if the keys are mutable and you change the key (like a string) after it has been used to index the table. Or is it possible to tell the table to copy any keys that are not in the table as they are entered into the table?
