Check for Perl Module

Sometimes you’ll need to decide on a course of action depending on the presence of a certain module.

The way you’d usually pull in a module:
```
use MODULE qw(SYMBOLS);
```

Instead of pulling in the module:

eval "use MODULE";
if (not $EVAL_ERROR) { # use English: $@ -> $EVAL_ERROR
    require MODULE;
  import MODULE qw(SYMBOLS);
}
