My use case is, i save [this](https://forum.crystal-lang.org/t/print-out-the-instance-methods-defined-class-or-the-path-where-the-current-class-is/4771/2) really useful snippets write by @asterite to, e.g. `~/Dropbox/common/crystal/lib/meta.cr`, then prepend this folder into $CRYSTAL\_PATH.

now, i can use those methods defined in meta.cr, like this:

```crystal
require "meta"

pp! "hello".methods
pp! String.class_methods

```
