Eliminate function lookup everytime when calling a function
e552e14 
Instead hold onto an `Rc` to the instructions and pass that to the
runtime.
@shsms
Merge branch 'main' into vm
7f98778
@shsms
Intern keywords once in context
268294d
@shsms
Simplify function execution from the VM
c4a9541 
To help with implementing funcall later.
@shsms
Update VM error messages to match the tree walker
6db95e4
@shsms
Merge branch 'main' into vm
e61b286

@shsms
Group defun instructions and params into CompiledDefun type
d182089
@shsms
Improve formatting
9de6244
@shsms
Improve variable names in defun compiler
0aeb44d 
This differentiates the `defun` keyword which is the name of the
function being called, from the name of the defun being compiled.
@shsms
Improve test, to be compatible with both VM and tree walker
de62f34 
They were both complaining about different `j`s earlier.
@shsms
Simplify defun compilation further
8ba26f6
@shsms
Check at compile-time that let variables are symbols
d6ee93d
@shsms
Add a name parameter to CompiledDefun

This will be needed when implementing `funcall` on them.
@shsms
Reuse Machine instance from TulispContext
fdba3fa 
Without this a `Machine` instance that has all the state won't be
available to make `funcall`s on.
@shsms
Move value setting functions to a separate module
b4a5db8
@shsms
Support storing CompiledDefun as values
