Recovering panics into errors

Experimenting with system memory panics

Import package:

import "github.com/PuppyKhan/catchpanic"

Add catchall with defer:

func foo() (err error) {
	defer catchpanic.ToError(&err)

	// panic prone code
}

There are actually 3 distinct types of panics in Go

• Recoverable user thrown panics
• Recoverable minor system panics
• Unrecoverable system panics

The benevolent overlords of Go deemed it impossible to catch all system panics, especially when it comes to running out of memory.

Fundamentally, the role of a garbage collector is to present to the programmer the illusion of an infinite free store.

If that illusion is broken, is seems reasonable to abort the program. -davecheney #facepalm
