[ruby-core:112514] [Ruby master Feature#19452] `Thread::Backtrace::Location` should have column information if possible.

Issue #19452 has been updated by rubyFeedback (robert heiler).


Perhaps this could be discussed as "one item" in an upcoming
dev meeting, e. g. the extensions ioquatix suggested in the
last some issues raised here. Since I love introspection I
am all in favour of what can be useful for us, when writing
ruby code, and wanting to get more useful information. (Note
that I have not thought through if I may need this, or not;
I am trusting that ioquatix is convinced it may be useful.
I have had very little exposure to Threads actually, and
none at all with Threads::Backtrace, so to me this is a bit
more of a niche topic. Guess I have to update my ruby knowledge
with zverok's new documentation. :D)

Feature #19452: `Thread::Backtrace::Location` should have column information if possible.
https://bugs.ruby-lang.org/issues/19452#change-101959

* Author: ioquatix (Samuel Williams)
* Status: Open
* Priority: Normal
----------------------------------------
I discussed this with @mame and it would be pretty useful if we could also get the column information from exception backtrace location, even if it was slow.

A POC:

```ruby
class Thread::Backtrace::Location
  if defined?(RubyVM::AbstractSyntaxTree)
    def first_column
      RubyVM::AbstractSyntaxTree.of(self, keep_script_lines: true).first_column
    end
  else
    def first_column
      raise NotImplementedError
    end
  end
end
```

It would be good to have a standard interface, so we follow the same interface as https://bugs.ruby-lang.org/issues/19451 and vice versa where it makes sense. I'll investigate it.
