regex!("...") should generate a const instead of a static

I am not completely sure about this, but it was strange to get a compiler error when trying to do:

const re: Regex = regex!("42");

The error message is (copied from the plapen):

<anon>:8:19: 8:32 error: constants cannot refer to other statics, insert an intermediate constant instead
<anon>:8 const re: Regex = regex!("42");
                           ^~~~~~~~~~~~~
<anon>:1:1: 12:1 note: in expansion of regex!
<anon>:8:19: 8:32 note: expansion site
error: aborting due to previous error

Shouldn't this work?

In-tree regex was removed in #21458 . This should probably be moved to https://github.com/rust-lang/regex

You are right! Thanks!
