Relicense to 0BSD, update mail address 
I've come to the conclusion that copyright mostly just stands in the way
of software development.  In my jurisdiction I cannot give up my own
copyright and 0BSD seems to be the closest thing to public domain.

The updated mail address, also used in my author/committer lines,
is shorter and looks nicer.  People rarely interact anyway.

_init() and _INITIALIZER -> _make()

interpreter: forward "argv" 2017-05-26 20:25:02 +02:00
Přemysl Eric Janouch 3e68a09ae1
Remove suck 
struct context::arguments stank, the "arg" special form stank.

The amount of lines this adds can be counted on one hand.

Implement dynamic scoping 
Okay, that was a PITA to not have.

But I think I'm set now, feature-wise.

Přemysl Eric Janouch ec7a0dc95f
Add "values"

Přemysl Eric Janouch 735dfd026a
Make and/or more useful 
Now they follow Scheme, they just aren't special forms here.
 2017-05-26 01:27:30 +02:00
Přemysl Eric Janouch 4358e6f324
Simplify runtime library initialization 
And remove the error printing side effect, just like that, at a cost.
 2017-05-25 19:41:27 +02:00
Přemysl Eric Janouch 5ae69c1cfc
Finish implementation of printing 
Now readds all syntax sugar and quotes strings properly.

Removed automatic line breaking and indenting since it is complicated.

Removed #ifndef since it stopped making any sense.

Make the lexer follow an unsigned string 
Much safer this way, allows omitting "unsigned char" temporaries.
