defining and calling functions

[ahdinosaur]

Operators:

• $fn
• $apply

but the question is: how do we "render" a Template::Function if we return a Value and there's no Value::Function?

okay i tried https://github.com/ahdinosaur/rimu/tree/functions but nah

new plan sketch:

1. rimu-expr
   • define Expression
2. rimu-value
   • define Function
   • Function is struct with "name" (String), "args" (Vec<String>) "body" (Expression)
3. rimu-env
   • defines Environment (previously Context)
4. rimu-expr-parse
   • parse String to Expression
5. rimu-expr-eval
   • evaluates Expression (with Environment) to Value
6. rimu

a side thought, is if Expression ends up being fully featured, then a Block (previously Operation) could end up just returning the Expression that represents itself, a Template could return the Expression that represents itself.
