tryit + verror = Verbosely try.

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.

$3

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.

$3

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.

Known issues

* Needs more/better tests and docs.
