A lightweight higher-order-function that doesn't compile
if a function you pass to it might panic. This probably
wont' work unless you're compiling your code with optimizations
enabled.
works when built with optimizations / release:
```no_build
doesn't work:
```compile_fail
Inspired by [this](https://github.com/dtolnay/no-panic) and [this](https://github.com/japaric/panic-never) but without requiring proc macros and corresponding long compilation times.
