The mail I provided a link to is only of interest if you're wondering
"is it really necessary for an Erlang implementation to have a finite
atom table, and is it really so hard to GC that table?"
If you're just interested in writing programs that work, it suffices
to know that
- in general, don't use 'list_to_atom'. (There are few legitimate
uses outside of debugging, it probably wouldn't hurt for the
documentation to say something along those lines.)
- it general, if something is a string (list), you should store it
as a string (list)
- the current Erlang implementation has a limit to the number of
atoms you can have. That limit is high enough so that this will
only cause problems if you're doing strange things, such as
creating atoms dynamically with 'list_to_atom'.
