API
---
This module exports one function that can be called in several ways
described below. In each case,
* f is the original function that might throw.
* g is a proxy function that wraps f, preserving context (this)
and arguments. If no error is thrown, it forwards the result.
Errors are silently ignored.
In case of an error, return hnd(err, ...args).
* Required prior knowledge: verror
Decorate potentially-cryptic errors with an error message errMsg that
ideally describes what operation you were trying to perform.errMsg must be either a non-empty string or an array.
It will be used as the sprintf_args to VError.errOpt are the options as described in VError.
There's also a method vtry.pr ("Promise") which works almost as above,
except it takes an async function f and returns an async function g.
As a special convenience, supplying 1 (the number) as f is a shorthand
for the identity function, so you can easily pass existing promises to g.
