module Error:sig..end
failwiths message value sexp_of_value raises an exception with the supplied
message and value, by constructing an Error.t and using Error.raise. As
usual, the sexp_of_value is only applied when the value is converted to a sexp or a
string. So, if you mutate value in between the time you call failwiths and the
time the error is displayed, those mutations will be reflected in the error message.
failwiths s a f = Error.raise (Error.create s a f)
failwithp _here_ s a f is just failwiths with the source code position tagged on.
We use Lexing.position rather than Source_code_position.t to avoid a circular
dependency.
