Pino: TypeError: this[writeSym] is not a function

[thisisarjun]

Hi,
I encountered the following issue, while using pino with process event 'uncaughtException'

`
const pino = require('pino')();

process.on('uncaughtException', pino.fatal);

asd.asd = 200;
`

I get the following error :
TypeError: this[writeSym] is not a function at process.LOG (/Users/asl/Workspace/todel/node_modules/pino/lib/tools.js:36:21) at emitOne (events.js:116:13) at process.emit (events.js:211:7) at process._fatalException (bootstrap_node.js:391:26)

Pino logger methods are not bound to their object. If you plan to use them as functions, you need to bind them yourself:

const pino = require('pino')();

process.on('uncaughtException', pino.fatal.bind(pino));

asd.asd = 200;
