Factor/Design issues

These are erg's ideas for language changes. If we ever reach a concensus on any of them, they will be moved to To do.

Should integers be sequences?

Should associative lists be first-class tuples or remain as arrays of 2arrays?

Should math operators such as + be overloaded for vectors?

Should at and nth be the same concept?

Erlang-style concurrency or 1:1 native threading?

Should call work on words?

The execute word would go away and call would be generic and replace the usages of execute.

Example:

 { 1 2 3 4 5 } \ even? filter

On the other hand, callable would no longer be a subtype of sequence, which would complicate macros that do sequence operations on quotations; they'd need to special-case words to avoid surprising the user with errors.
