(code ast)Transforms your AST back into code
ast: The nested sequence of [:keyword & content] which MUST follow the
same structure as the result of (parcera/clojure input-string)
Returns a string representation of the provided AST

(failure? ast)Checks if ast contains any ::failure instances.
NOTE: This function is potentially slow since it might have to check the complete ast to be sure that there are no failures.
Whenever possible, prefer to handle errors directly appearing in the ast
