(the JSON data is invalid) A try catch is a way to evaluate an expression while letting you handle the successful case as well as the errors encountered. The general syntax of a try catch expression is as follows. Syntax Notice that although the keyword catch is used in the try expression, there is not a catch expression within the try expression. It returns the value of Exprs (a sequence of expressions Expr1, , ExprN ) unless an exception occurs during the evaluation.

To generate Erlang code dynamically, you have until now had two choices: you could either create plain tuples according to the "abstract format" as generated by erl_parse (which is messy and has many special cases to keep in mind), or you could use the API functions in the erl_syntax module (which offer more abstraction, but can get pretty verbose).
