    (compile ast &opt env source lints)

    Compiles an abstract syntax tree `ast` into a function. Returns a 
    new function and does not modify `ast`. If compilation fails, 
    returns an error struct with keys `:line`, `:column`, and `:error`. 
    If a table `env` is given, specifies the environment of the fiber 
    used during compilation. Optional argument `source` is a string or 
    keyword that is a source path for better errors. If a `lints` array 
    is given, linting messages will be appended to the array. Each 
    message will be a tuple of the form `[level line col message]`.
