That's not funny, it's expected, as `load` deals exclusively with paths, and `require` does not generally deal with paths.  Example:

```
File.write("x.foo", "p 1")
load("x.foo") # prints 1
load("./x.foo") # prints 1
require("x.foo") # LoadError
require("./x.foo") # LoadError
```

Now, if you have a path ending in `.rb`/`.so`/etc., you can get require to accept it directly.  But in general, `require` does not deal with paths.  I don't think we should add Pathname support to `require`.

Feature #19985: Support `Pathname` for `require`
https://bugs.ruby-lang.org/issues/19985#change-105146

* Author: vo.x (Vit Ondruch)
* Status: Open
* Priority: Normal
----------------------------------------
It seems that RubyGems / Bundler `require` method overrides of accept `Pathname` as and argument

~~~
$ ruby -rpathname -e '
pa = Pathname.new("test")
require pa
'
<internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- test (LoadError)
	from <internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require'
	from -e:3:in `<main>'
~~~

while plain Ruby require does not:

~~~
$ ruby --disable-gems -rpathname -e '
pa = Pathname.new("test")
require pa
'
-e:3:in `require': no implicit conversion of Pathname into String (TypeError)
	from -e:3:in `<main>'
~~~

This inconsistency is surprising. It seems that RubyGems / Bundler developers think [1] that Ruby `require` should also accept `Pathname`.
