[ruby-dev:42544] Re: [Ruby 1.9-Feature#3917] [proposal] called_from() which is much faster than caller()

Hi Run Run, thank you for your comment about Kernel#caller.

Ko1 has the same idea as what you proposed on #1906.
He want to change return value from "filename:linenum: in `name'"
to structured data type which is very similar to what you proposed.

And I already proposed to add new argument to Kernel#caller() in order to
specify backtrace depth, instead of adding new top-level function.
Please check out 'Another Solutions' section on this ticket.


Ko1, could you read #1906 if you change return value of caller()?
