aa

Scheme dialect for 9front, the only Plan 9 operating system that is actually worth doing anything with.

This was originally a port of fe, but is now moving in its own direction (R7RS).

What's up with the name?

• My name is Parentheses, for we are many. AAAaaaaaAAaaaaa.

Notes

• all numbers are of double type
• C null-terminated string, so no binaries supported
• characters escaping isn't there
• no idea wth let is doing currently

• tail call optimization
• bytecode vm?
• stop making stupid dad jokes
