sforman e7ac46fd7b A spec doc for Thun. 
It's not very good yet, or formal, "but it's mine and I love it."

sforman c0fa319c9c Crude type checking. 
I forget why I was doing "not not" so I made it a little more clear.  In
practice this is regressive:  The built-in "isnt_bool" function should
be in the dictionary?  Or prohibit type checking and let the bugs flow?
Rely on inference to prevent bugs that would pass the non-checking
versions of the functions?  Hmm...

sforman 373666bf39 Name Boolean ops. 
So they don't overshadow the defs for the short-circuiting combinators.

sforman 1089ab7c24 Error type (not just a string.) 
This is mostly for fun, but I bet it comes in handy, eh?

At the very least, it's a nice catalog of the possible errors that the
basic Joy system might encounter.

sforman 200c390fd5 Initialize dict with defs. 
Just sqr for now, but it shows that it works.

I would like to return Results from add_def but it makes using foldl
slightly tricky,  not a lot, just slightly, and my brainpower is low at
the mo'.

sforman edfd7c526f Look up words in the dictionary. 
If they are not built-in, which means you can't "shadow" built-ins with
"inscribe", which may or may not turn out to be what we want?

I have to check into this: the Python version has "bool" and no
"truthy".

sforman 9917a2cfba Refactor pop_int. 
I don't like passing the stack through isnt_int but that let's you chain
with andThen.

There's probably a clever or idiomatic way to not do that and couple the
stack to the result without passing it through the type checker function
but I don't know what it is right now, and this works.
